Brother

A brother is someone who constantly beat you up, break your dreams, supresses you, make you look bad in front of your patents, eat your candy, snitch to your parents and wake you up with a knife one inch from your head!

Still (it appears) your parents say that it's your brother and you should love each other unconditionally. If you're home alone with your brother for a day or two, i wouldn't wonder if you newer woke up again, or woke up with a pillow presses to your face.

But on the other hand, if you where the only child in the house, you would probably suffer from diabetes...

Me: "My back hurt and i don't believe in myself"
Friend: "I'd hate to have a brother"
The most anxious, depressed and unpopular guy at school: "I have 3"
