Anyone who has a sister know it's like having a built-in best friend and archnemesis at the same time. One minute you're borrowing her clothes from your self-proclaimed shared closet (your sister's closet) and the next, you're screaming because she took something without asking. Because as all true sisters know, she can take your stuff, but the second you touch hers… it's war.

Growing up with a sister means you used to the passive-aggressive communication across the dinner table, you've had many full-blown fights over something ridiculous (and it's probably over who gets to sit in the front seat), and no matter how many times you swore you'd never speak again, somehow, you always end up sending each other TikToks later that night like nothing happened. Sisters are the only people who can roast you worse than anyone else, yet also be your biggest defender when someone else tries to do the same. And yet, we wouldn't trade them for the world (until they do something to get on our nerves).

  • It’s true. Growing up, you can’t wait to move out and have your own space. No more fights over the bathroom in the morning or mysteriously missing clothes. But once you’re an adult, you actually miss having your sister around. Suddenly, you’re sending each other unhinged texts daily, and the second you leave your parents’ house, you’re already counting down to seeing her again.
