Is it normal to be creeped out?
One of my friend's dad's slapped my butt the other night at the bar. I ignored him, pretended I didn't notice. Later on, he started yelling some kind of conversation at me when I was up against the bar trying to buy a beer and grabbed me by the arm to try to turn me around. Once, in the past, he told a guy my age (while I was standing there) that he wished he was young so he could screw young gals again.
Needless to say, I am careful to avoid being alone with him.
