Oh, dear Googley...
I know I would feel the same way - and be mad.

This guy just sounds like a jerk. Try to just let it go. Be the better person and all that. I bet he's a jerk to a lot of other people. It's not your problem... you understand computers, you understand the program... and he can go on about whatever he wants to. I know it is hard. (I am really trying to work on this one too). But people can say all kinds of cr*p. I'm sure there were those around Bill Gates in college who were like, "he doesn't know anything." Didn't Bill Gates even drop out? People will talk and go on about whatever they go on about. Just let it roll off your back.

Hugs
