1. There's nothing better than having close BFFs who you can share any and everything with.
2. That is, unless your BFF also happens to be your sibling!
3. After all, who knows you better than the person you grew up and created lifelong memories with?
4. You're not afraid to be your true, authentic self, even if that means showing your competitive side.
5. Being best friends with your sibling means you get to be as blunt and honest as you want at all times.
6. And you have built-in referees for all of your fights since you have the same parents.
7. You can't get away with the same shenanigans as you do with your other pals, because your sibling knows you better than that.
8. You're closer than the average siblings because as friends you also run in the same social group, which means you ~ share ~ each other's friends, too.
9. You have your go-to ways of solving your problems that you probably wouldn't do with your other friends.
10. And you even have your own unique way of communicating.
11. You're always happy to celebrate each other when you feel proud of their accomplishments.
12. You stick by each other no matter what; traumatic experiences happen, but they can't get in your way!
13. But that doesn't mean you're above playing pranks and messing around when the opportunity presents itself.
14. No matter how old you get, your childhood always comes up and you act like you did when you were kids.
15. You never hesitate to come to your siblings' defense (at least, the best you can).
16. When you're BFFs with your sibling, you don't have to explain all of your flaws and quirks.
They already know everything about you!
17. Sometimes things can get unintentionally inappropriate, since your relationship with your sibling isn't the same as all your other friends.
18. Not only do you share common interests, but since you're genetically linked you also make the same faces and have similar reactions to everything.
19. You always have each other's backs, no questions asked.
20. Because the bond you have with your sibling isn't just about family.
21. It's also about friendship.
