Sister-Friends

Sister-friends are girls that are so close, they could be sisters.. They can't live without each other. Side by side or miles apart, they will always be close. To each other, they are unforgettable. They act weird and smack butts without giving it a second thought. When they are happy, you are. When they feel pain.. you do. Living without them isn't an option. They are you're life. <3 You love them.

Bailey: I'm moving....
Sofia, Avery, Rachel, Lily, Teagan, and Claire: No you're not.
Bailey: yes, i am.

Everyone else: not if we have something to do with it.
*smacks booty* Bailey: whatever.
Mia: it doesnt matter. there is no way you're forgetting us.

Bailey: i don't think that's possible.. (laughs)

Everyone else: you'll always have us. and we'll be there for you.

Bailey: as you have always been! You're my sister-friends
