My best friend and I

My best friend and I get along with each other quite well. But we are so different. He is a quite funny outgoing guy but I am very serious. He is an athletic boy and is able to play all kinds of sports but I am only smart on study. My friend is wild and I am calm. He is tall, thin, strong, with shorthair, And sometime he is very careless and lazy. On the other hands, I am short, fat, weak, with shorthair. He is very helpful because I am very lazy and don't want to do any sports. And I will help him with his study. 
I think our friendship is beautiful.
