Being a big sister is one of my greatest joys. I love my little sister.

Even though she's only two years younger than me, it feels like we're in completely different stages of our lives. It creates a unique experience.

Here are 15 moments only big sisters experience as they watch their little sister grow up:

1. Being proud of her and her accomplishments.

YAS, sista. You got this.

2. Helping her figure out future plans.

"Is that going to make you happy?"

3. Prom.

Senior Prom. Emotional. Beautiful.

4. Heartbreak.

At some point, little sisters get their hearts broken. Big sisters are there to pick up the pieces and put them back together.

5. Stealing clothes.

If your sister is close in age and about the same size, clothes are going to be exchanged. Bottom line.

6. Giving life advice.

We're older and a bit wiser.

7. Bonding over similar experiences.

"I used to go there almost every day!"

8. Cherishing time spent under the same roof.

At some point or another, big sisters begin to realize that it won't be long before our little sister will be living on her own.

9. Being there for her even when she pushes you away.

Especially when a girl is 18, she pushes people away; sometimes it's not even on purpose. I was 18 once, and I know even when I pushed the people who mattered the most away, I still wanted them to be there for me.

Big sisters never waver.

10. Being the ultimate wing-woman.

Girls just wanna have fun, right?

Being a big sister is fun, especially when you have a little sister like mine.
