I don't know.

I can notice. I'm not dumb. I know you're angry and I know is with me. But I don't know your reasons and that's quite hard to me.
I can tell you, you're not my best friend 'cause you go with me to all the parties and get drunk together everytime as possible. You're my best friend because you know everything about me; and maybe I don't know everything about you but I know you more than anyone.
I can't take that as a victory, because in times like this, knowing a lot about you is not enough.
I'm sorry if I made something to do you wrong, but you I love you brother, and I wouldn't do anything to make you feel bad.
