Sorry. I've been pissing people off without understanding why for years. Usually because I'm so lacking in self-confidence that I always try to take up as little of somebody's time as possible..I just automatically assume that my presence is a burden and that they'd like to get rid of me as quickly as possible. Then, they get angry because they think I'm being stand-offish or rude or disinterested, and I'm unable to tell them that I really don't mean to be rude, but that I just didn't want to waste their time. Anyway, probably not the same as your situation, but I hope you feel better!
