There is something special about the relationship between sisters. Sure, you know how to push all their buttons and can annoy them on command, but you also have a built in best friend that has to love you and knows you better than anyone in the world. Here are some reasons why your sister is the best friend you could ever hope for!

She understands you

Sisters understand you on a level that no one else ever will. Not only does she know your Starbucks order, which jewel tones are your favorite, and the name of your future pug (Pickles the pug if you were wondering), she's also the only one that can unravel gibberish like, "Who is the guy with the face that always says the things in the voice?" or "My hair was doing the weird triangle thing" or "I just feel so floopsy today!"

You're Weird matches her Weird

You've spent so much time together that you have cultivated a unique brand of mutual weirdness, and being weird together makes it ten times more fun! Go get disproportionately excited about dinosaur chicken nuggets, take adorable sister Instagram pictures all over town, find cat memes on the Internet. Whatever your sister fun looks like, it's great knowing she's always there to have fun with/be weird with/bother until she plays with you.

The competition

Sisters can get overly competitive about pretty much anything: who gets the best grades, who has the best taste, who can sing and dance best to Beyonce's "Single Ladies." A N Y T H I N G . But you know what, you love her for it because she makes you push yourself and the competition makes life more interesting.

Great Compliments

"I love your nose bump," "you're simply majestic," "you are a ray of sunshine in a world of rainclouds," "your nose is so boopable," and "you have mermaid hair" are just a few of the personalized compliments my sister and I have thrown around in the last 48 hours. Sister compliments are the best because they know all your insecurities and all the things that you love most about yourself. Put that together and you get the most empowering, uplifting, and strangely wonderful compliments ever!

Honesty

If you want an honest answer to "What do you think of my new bangs?" or "Do you think these gauchos will come back in style?" then you can always talk to your sister. They've known you so long and are so comfortable with you that they are in no way afraid to hurt your feelings.This can either be really good or really bad! But at the end of the day, they're blunt with you about what matters when others won't be, and that's what matters.

She has pictures of you from middle school, so you need to keep her on your good side.

It's true. This chick has some quality blackmail. I'm talking braces, middle school dances, and your Jonas Brothers phase (though let's be real, you're not too ashamed of that). Keep your friends close and your sister closer.

You protect each other

You may be brutally honest with each other, but if anyone else crosses your sister, they better watch themselves. You always have each others backs when it comes to mom and dad. And not only does she protect you from others, she protects you from yourself. Thinking about dating the no-good boy who says things like "'sup" or "women belong in the kitchen." Yeah, that's not happening on your sister's watch. It's great that there is someone there who things you deserve the best the wold has and who always watches out for you. And you wouldn't trade that for the world.
