My name is Liam, and I'm four years old. Well, I was four, until I found this shiny artifact at daycare. It looked like a cool toy, so I decided to take it home.

My big brother Danny, who's 16, never lets me do anything fun. He's always telling me to behave and not to eat too many cookies. So I thought, why not be him?

That's when I found out what the artifact could do. I was pretending to be Danny when suddenly, I was looking at myself. Or rather, my four-year-old self.

Danny's face on my little body was priceless. He was so shocked! I, on the other hand, felt pretty cool being tall and big.

Our parents were shocked too when they saw us. But they'd been planning their date for weeks, and they said they weren't cancelling.

So they left me, big Liam, in charge of little Danny. This was the total opposite of how things usually were.

At first, I was excited. I could finally eat all the cookies I wanted, and Danny couldn't stop me.

But then, I had to start taking care of Danny. Suddenly, being big wasn't as fun as I thought it would be.

I had to make him lunch, help him get dressed, and even read him a story. It was exhausting.

And Danny wasn't happy either. He missed being a teenager and didn't like being treated like a baby.

I tried to cheer him up by playing with his favorite toys, but he just sat there, looking miserable.

Then, he started crying. I didn't know what to do. I felt terrible for making him feel this way.

That's when I realized that being older wasn't just about having more freedom. It was also about taking care of others.

So, I did what I thought Danny would do. I hugged him and told him it was okay. That we'd figure this out together.

I decided to use the artifact again, hoping to reverse the age swap. But nothing happened. I guess it only worked once.

I felt desperate. Our parents would be home soon, and I didn't want them to see us like this.

But then, Danny tugged at my shirt. He was holding another artifact, just like the one I'd found.

He'd found it at daycare too, but he'd been too scared to use it. I guess he didn't want to be a baby again.

I took the artifact from him and held both of them together. Suddenly, there was a flash of light, and everything went back to normal.

I was back in my little body, and Danny was back in his. We both sighed with relief.

When our parents came home, they were surprised to find us hugging. They didn't know what we'd been through that day.

But we knew. And from that day on, we understood each other a little bit better.

Danny stopped treating me like a baby, and I stopped wishing I was older. We were just happy being ourselves.

And the artifacts? We buried them in the backyard. We didn't want anyone else to go through what we did.

In the end, being older wasn't all about eating all the cookies I wanted. It was about responsibility, understanding, and caring for others.

And being younger wasn't all about being taken care of. It was about learning, growing, and being patient with myself.

So, I guess we both learned something that day. And even though it was scary and confusing, I wouldn't change it for anything.

Because that's the day I learned what it really meant to be a big brother. And Danny learned what it was like to be me.

And we both learned that no matter our age, we will always be brothers. And that's the most important thing of all.

So, no matter how old you are, remember to be kind to your siblings. You never know when you might have to swap places.

And if you ever find a shiny artifact at daycare, maybe just leave it there. Trust me on this one.

Because being yourself is the best thing you can be. And no artifact can change that.

So here's to being four, or sixteen, or whatever age you are. It's all part of the journey. And it's a journey worth taking.

Because in the end, it's not about how old you are. It's about who you are. And that's something worth celebrating.

So cheers to us, cheers to growing up, and cheers to being just the way we are. Because that's what makes us, us.
