• I was two months pregnant when my sister asked to move in with my partner and me.
• At first, our dynamic was great, and we loved living together. Then, it got a little tense.
• We were in different places, and she eventually moved out, but we're now as close as ever.

When I was two months pregnant with my first child, my older sister called and asked if she could move in temporarily with my partner and me. She needed a fresh start and had decided to move interstate from the Gold Coast, Australia, where we grew up, to Melbourne, where I had been living for about a year.

At the time, my partner Sam and I were living in an old 1950s two-bedroom flat. I'd lived with my sister before in my 20s, so I knew she was easy to live with. After chatting with Sam about it, he said he didn't mind her crashing for a while until she got on her feet.

And so, a few weeks later, my sister arrived on our doorstep.

At first, living together was great

Luckily, my partner and sister have always got on well. Years ago, the three of us traveled through Laos and Thailand together, then later we backpacked around Cuba with my sister, so there was a lot of shared history between us.

Those first couple of months living together were really fun. My sister landed a corporate job in the city and quickly settled into Melbourne life. Melbourne is a cosmopolitan city that's known for its vibrant festival scene, which we embraced wholeheartedly. Every weekend, we would head to an international festival or cultural celebration together.

The household dynamic worked really well to start with. My sister paid rent, which helped us financially. We took turns cooking, and everyone got along. I remember coming home to find my partner squeezing my sister's blackheads on the couch one night and thinking, "Wow, this has taken their bond to a whole new level."

It was a time of transition, and things became a little tense

But it was also a really hectic time for Sam and me. I was battling the trials and tribulations of the first trimester of pregnancy and working full-time as a journalist, while Sam was trying to build his remedial massage business.

Within a few weeks of my sister living with us, Sam proposed to me. We'd been together for about eight years by that point, and with a baby on the way, marriage seemed like the logical next step. Suddenly, there was a wedding to arrange, which added to the stress levels.

After the wedding and honeymoon, I started to feel like the living arrangement wasn't really working out. My pregnancy was getting further along, and my hormones were raging. My sister was in a different phase of life. She was in party mode, while I wanted to nest, decorate the baby's nursery, and relish that so-called newlywed bliss that everyone talks about.

After a while, things became a little tense in the household. I began to feel like we needed our own space. I'm not very good at being direct with people, so I'd discreetly ask my sister how the house hunt was coming along. She eventually got the message and found a flat for herself after five months of living with us.

My sister moved out, and our relationship returned to normal

As soon as she had her own place, our relationship went back to the way it had been before. Sam and I were able to spend some quality time together alone before our son was born and our lives changed forever, while my sister could party guilt-free at her own digs.

Our son is 10 now, and my sister and I live in different states. She has a beautiful little girl of her own and has left the partying days behind. We're still as close as ever despite the eight-year age difference between us, and we often reflect on the happy memories we made in Melbourne together all those moons ago.

• When my partner and I were in our 20s, we moved in with Billy and Fern, a couple in their 50s.
• It was a great living situation, and we became close during our time renting a room from them.
• Though we've since moved on, we've remained lifelong friends.

When we were in our 20s, my partner Sam and I decided to do a working holiday in Banff, Canada.

Initially, we rented a room in a three-bedroom share house with two other couples who were close in age to us. It was loads of fun, but nobody did much cleaning, and there was a fair amount of drinking and partying.

Sam got a job with the town of Banff and soon he befriended this Canadian guy named Billy. Billy is one of those larger-than-life personalities; he's high energy and extremely likeable. Everyone in town knows him, and he's affectionately known as "Billy Banff."

One day, Billy mentioned that he and his wife had a room available in their cozy two-bedroom property. After chatting with me about it, Sam told Billy we'd love to take it.

We lived together well

I'll never forget the day we moved in. I met Billy's wife, Fern, who's a wonderfully warm, very calm, grounded person. She's the yin to Billy's yang in a lot of ways, and the pair complements each other beautifully.

As we talked through the finer details of the rental arrangement, I asked her if I could have a set of keys for the property.

"Oh, honey, we don't even know where they are," she said, smiling. "We never bother locking the house!" That's the kind of trusting, beautiful people Billy and Fern are. Their house is always open and full of loved ones.

When they showed us our room, they'd left a bottle of Yellow Tail merlot from Australia on the dresser for us, as a nod to our home. We felt so welcome.

At that point, Billy and Fern were in their 50s, while Sam and I were 29 and 26. Despite the age difference, the living arrangement worked really well. Fern and Bill were fun and young at heart, but also very caring and nurturing. We all helped out with cleaning and often shared meals together.

I used to love coming home after a waitressing shift to find Fern on the veranda, relaxing and taking in nature. We'd have deep conversations about love, life, and everything in between.

Sometimes, if Billy was home, we'd crank "Moves Like Jagger" by Maroon 5 and dance around the living room like kids. I also played "A Horse With No Name" by America over and over; it had been featured by our favorite TV show at the time, "Breaking Bad," and Billy and I often sang it together. It became a bit of a theme song for that chapter of my life.

We moved out, but we've stayed in touch all these years

When we eventually decided it was time to move on from Banff, the feeling was bittersweet. It was springtime when we left. The deer were out in full force and the sun was still shining at 9 p.m. As a final farewell, Fern made an amazing feast for us and we sat around the fire drinking wine. It really felt like home.

After we left Banff, we moved to London for a year and then returned to Australia. As fate would have it, Fern and Billy's daughter Penny lives on the Gold Coast, where my family is based, so we've been lucky enough to catch up with them over the years. In 2019, we even took our kids to Canada to show them Banff, which still feels like our "happy place."

On our most recent catch-up on the Gold Coast earlier this year, I was walking through a beachside park when I heard someone singing a familiar tune with a thick Canadian accent. "I've been through the desert on a horse with no name. It felt good to be out of the rain," they sang. I could not wipe the grin off my face as I turned and saw Billy standing nearby, his arms outstretched and ready for a bear hug.

Whenever we get together with Fern and Billy, it's always like old times. They're more than lifelong friends. To us, they're family and always will be.

• My parents met while traveling in 1971 and were married six months later.
• I've learned a lot from their marriage of over 50 years that has inspired me in my own marriage.
• They've shown me that conflict is healthy and normal, and so is having different interests.

My parents recently celebrated their 53rd wedding anniversary. They met while traveling through Spain in 1971 and married six months later.

My mom has always said it hasn't all been rainbows and butterflies. But they've worked through the hard times and persevered with their marriage, even when things have been tough.

Though I'd always secretly been terrified of commitment, I was also lucky enough to have their solid example of what a strong marriage could look like, and I married Sam — the love of my life — in 2015. The lessons I've learned by watching my parents' marriage have made it all the easier to walk in their footsteps, and now Sam and I have been happily married for a decade.

They taught me it's OK to have different interests

Aside from their shared passion for travel, my parents are opposites in so many ways. My mom loves art and languages, going to the theatre, and watching movies.

My dad, on the other hand, has always enjoyed playing and watching sports, collecting stamps, and doing crosswords. In his 50s, he randomly decided he wanted to run a marathon and ended up doing four. My mom has never run a day in her life.

However, they share a few fundamental values that have always kept them on the same page: a love of learning and acquiring general knowledge, a belief in seizing the day and making the most out of each moment, the importance of keeping the flame alive, and the belief that family always comes first, no matter what.

My husband and I are also polar opposites in many ways, but like my parents, our core values are aligned.

Growing up, I saw that conflict is normal and healthy

While I was growing up, my folks often had heated arguments. Sometimes, there would even be periods where they weren't speaking together because they needed to cool off.

However, my parents always resolved the issue with respect and open communication. Through watching them, I learned that conflict in a long-term relationship is unavoidable and normal. There are bound to be differences in opinion, values, needs, and wants, but it's how you handle and resolve the conflict that matters.

They showed me the importance of space in a relationship

My parents have always made a habit of giving each other space — space to pursue hobbies they enjoy, space to travel independently, and time alone to recharge when needed.

My mom is hugely independent. During my childhood, she worked hard, saved up, and took my sisters and me on international trips while my dad stayed home and continued working. She's always said that it's important to be your own person and to follow your dreams.

My husband and I are similar in that we both have our own interests and give each other space in our relationship. We take turns going on solo international kid-free holidays, then come back recharged and ready for family life. Having downtime from each other helps us to keep the spark alive and to appreciate what we do have even more.

I know that marriage takes work

No marriage is perfect. Most of us derail at some point in our relationships, but if you truly love each other, you can usually get it back on track.

I know there have been times when my parents' marriage has been on the rocks. There have been enormous life challenges to navigate, and both of my parents would admit they've made mistakes.

But ultimately, they love each other deeply. This all-consuming, enduring love has helped them tackle every hurdle together and emerge stronger.

Of all the lessons they've taught me about relationships, this was the most important: Love is worth fighting for. Always.

• We wanted to go to our friends' three-day wedding, but leaving our kids was going to be tough.
• We decided to rent an apartment big enough that my parents could come with us.
• They watched the kids while we went to the wedding events, and we all had a great time.

Parenting during the early years can be tricky, especially when your little one wants you and only you. Your social life often gets put on the back burner, and I struggled with this when I became a mom.

Last year, my husband and I were invited to our friends' three-day wedding on the Gold Coast, Australia, where my folks are based. These particular friends know how to throw an epic party, so we really wanted to be there to celebrate with them. My husband and I were also desperately in need of a little kid-free adult time, where we could let loose and reconnect with our younger selves again.

However, our youngest daughter was still quite clingy with me. Our older two kids were 5 and 9 at the time, so we knew they would be fine if they had a three-day sleepover at my parents' house, but the 2-year-old wouldn't hear of it.

In the lead-up to the wedding, my husband and I deliberated about what to do. Hiring a babysitter around the clock was out of the question, and it was going to be hard for my mom and dad to have the three kids at their place, which was about a half-hour drive from the wedding. So, my husband came up with a plan.

My mom and dad came with us to watch the kids

"Why don't we pay for your mom and dad to stay around the corner from the wedding?" he asked one night over dinner. It sounded like a good idea to me, so I asked my folks if they would mind, and they said they'd love to. After all, who doesn't want a mini-break in an apartment on the beach (even with three little kids to entertain)?

We rented the most perfect three-bedroom apartment with enough room for all seven of us so my parents could stay and watch the kids while we went to the wedding events. It had views of the Gold Coast and the occasional migrating humpback whale cruising past. There was a playground close to our apartment, and it was a short walk to the local shops. Best of all, the hotel where the wedding guests were staying was a two-minute walk away.

When the big day arrived and we checked in, the kids were so excited about the setting, they barely registered it that night when it was time for my husband and me to slip out to attend the first wedding event — a cocktail party.

We got glammed up, enjoyed a few drinks, and then returned to the apartment to kiss the kids goodnight before continuing the festivities. It was perfect.

The next day was the day of the actual wedding. We spent the morning with the kids and my folks on the beach, then walked two minutes down the road to the bus stop, where transport was waiting to take us to a picturesque wedding venue in the next suburb.

It was the perfect arrangement, and we all had a good time

We had the most amazing time at the wedding and loved that we were still close enough to go back to the apartment in a taxi if the kids needed us. Luckily, they didn't — they were having too much fun with Nana and Pop.

The third day was a recovery day. We had a boozy brunch at a local surf club, and then that night, we headed back to the same venue where the welcome cocktail party was held for impromptu post-wedding drinks with our friends. We had a ball and crept into the apartment at 3 a.m. feeling like two naughty 20-somethings.

Overall, paying for a larger apartment so our parents could stay with us and babysit while we attended our friends' wedding worked amazingly well. It meant we had people we trusted watching our kids, and the kids felt safe being with their grandparents, so they didn't need us.

We all ended up having an incredible three days. Mom and Dad made memories with the kids, while my husband and I danced and frolicked and felt like we were in our 20s again.
