Sister, sister. Sometimes, our besties are just basically family. If they've been around for awhile, odds are at one point or another they've called your place home, or just helped themselves to your closet full of clothes. Growing up with a brother meant a whole lot of teasing and looking at gross stuff. He made fun of your Justin Bieber phase, and maybe accidentally ruined a Barbie doll or two. Of course you love him, but having a sister has always low-key been a dream of yours -- and your bestie is basically that. There are many signs your best friend is like a sister, even if you're not bonded by blood.
She's your soul sister. At 2 a.m. when you need someone to run to your room with a pint of ice cream, she'll be the first one you call. When you're obsessing over a new guy, she'll be the first one you tell. You girls wouldn't want it any other way.
Sometimes you're surprised you're just sisters from another mister, because your brains are just so in sync. She might not always finish your sentences, but something in the stars will tell her that you're craving egg rolls, too. Suddenly you'll be getting takeout with her and wondering if telepathy is real.
We all love our BFFs for all they do for us, but having a bestie who's basically a sister is a whole new ball game. Here's the seven signs you should look for in your friend-turned-family.
