As a girl, having a big sister can be one of the best things to happen to you. Big sisters are good for just about everything -- advice, a role model, comedic relief, a built-in best friend, and a confidante. As a little girl, you look up to your sister and even want to be exactly like her (and I mean exactly). You admire her looks, her friends, her everything. You are proud to be her sister because she is the best person you know. If you were fortunate enough to have a sister who would pay attention to you and teach you things, then you had the best role model you could ask for. You watch your sister make mistakes and learn how to avoid some of them -- thanks for the sacrifice, Sis.

You constantly have a friend you can talk to about anything. Big sisters are always the best when it comes to boy advice. She will agree with you when you say boys are stupid, and she will tell you that you deserve the best. Because she does, too. She will tell you what it's like to find that one boy who will treat you right forever because she's found one herself.

Your sister is your number one influencer on your fashion sense. Meaning, she won't hesitate to tell you what looks absolutely ridiculous. It might be harsh, but at least you look good. Sisters are usually on your side when you and your parents are arguing, which is comforting. They have been there, done that. You and your sister have inside jokes that other people just don't understand. I guess that's the point of inside jokes, but ones you share with your sister are just better.

So thank you, Sister, for all the lessons, the memories, and for being the best role model and friend to your little sister.
