If you wanted to say anything to that guy you should have said it the night it happened. It became old the next day. If it happens again THEN you can say something. But don't go bring up old shit.

Your at a club, there's going to be tons of guys there, drunk guys wanting to talk to your girlfriend cuz that's all some guys go to clubs for, to pick up girls. You got to remember that before you even go in them doors.
