My little son who's 6 told me that when his dads friend was round he was pinching him, they were playing a PS3 game at the time, so it wasn't a tickling/play fight thing going on. I believe my son because the friend called him pinocchio and looked irritated. what kind of person would do this is he some sort of sadist? my son was rude to him once and I think it was payback time in some warped way.
