"I dislike you"

Have you ever met that person that just irritates you, gets under your skin and just p's you off? Sadly, I have to admit that's my 13yr old brother. He drives me beyond crazy. Everything he does just irks me and I can't explain why, he doesn't understand what "leave me alone" and "stop" means. He drives me crazy, he never stops he has a really big condescending attitude towards everything I say and do AND on top of that the kid just does stuff that I'm like aren't you suppose to be smart? I don't know he irks me, I don't know why, but everything he says and does I'm just appalled by and I just don't know how to explain how much I dislike this child. My dad keeps saying I'm going to make him hate me but honestly? The kid already drives me crazy, you know when you hug family you feel like family? With this kid once in a blue moon when he does ask for a hug? I just feel nothing. Emptiness? How bad is that? When you feeling nothing for your brother? That's not good at all. Especially when you... dislike your brother...
