Is it just me?
I've got a couple neighbors who used to bug me like that. One of them got the hint after I constantly ignored him, and the other doesn't seem to want to talk to me anymore after the "wheelbarrow incident."
I agree that he probably doesn't have any skills of his own, so he's got a guy for everything he needs done. I'd bet money that's how his father was, too. Some people just can't comprehend that others can have multiple skillsets outside of their current profession.
