People grabbing me makes me very nervous. I don't tolerate it, and usually just jerk back or jump. It's an involuntary response.
My father, for reasons unknown to me, enjoys slapping me on the leg to emphasize his point when he gets excited. It's not a hard slap, but it does hurt a bit, and it's incredibly annoying. He also refuses to say "excuse me" when he wants me to move out of the way, and instead either pushes me or guides me by shoving me around. I really can't stand this, and I always turn around and yell at him.
Oh, he doesn't do it just to me, by the way, it's just an annoying habit he has with everyone.
