Brother is when you need help most. He will appear at the first time. He may not be able to help you, but he will appear and stand next to you. He will always cry with you, laugh with you and suffer with you.
A brother is the one who raises his middle finger and leans his mouth to you when he's free, saying you're an idiot, but he's the first one to jump out and help you when he's free. A brother is someone who swears at you and claims that he doesn't bother others when he sees you, but when you are upset, he can drink beer with you until dawn.
