I hate/dislike my uncle??????

To be honest, I think your uncle is a walking, talking, ironic oxymoron. He seems to be a freeloader whom likes to control others' lives. I would use him as a prime example of what you DON'T want to be when you get older. It sounds like he has some kind of mental problems. I'd personally try to avoid him as best as i could, if i were you, that is. Then again, you may or may not have the same opinion whatsoever.
