Actually, this just happened to me a couple days ago. A went over to a buddy of mines house the other day. And he didnt look real pleased to see me. So I asked him whats up, and why he looked so pissed. Just jokingly I said, Oh you must not like me huh, and dont want me here. And, he said truthfully no I really dont, and so I stood up, and left.

You think you know people, but I guess you never really do.
