She's young and talkative. In the middle of her conversation with a guy she says "..all boys are dumb". The obviously single guy says "what do you classify as boys?" and she says "all men are boys".
I finally got enough and said "Any girl who says all boys are dumb better be a virgin or lesbian because no girl will sleep with a dumb guy". It got awkwardly quiet as she shuts up and started dealing, all the guys at the table go quiet too. Then an older guy says "You just left yourself way opened with that one" and I said "hey, no one else got the balls to stand up for us boys so it'll have to be me".
After that, she was nicer to me than all the other "boys". lol.
