Honest question: do some people just get a thrill out of coming off as a bitch when you first meet them? Scenario: I'm letting a girl maybe older than me by 3 years go ahead of me in line at the grocery. Says "thanks, you should trim your beard it looks a bit messy"
So I snipe back with "Yeah sorry about that, every year I grow it and donate the money I would spend on caring for it to the cancer foundation" (which I actually do)
Then she kind of just went quiet.
I would guess it's a combination of social ineptitude and attempt at flirting. Like, "I'd think you were pretty hot except for that beard." Except not quite.
