Im going to make this short. Im doing a group presentation and this girl asked me if we couldnt go first. I said no, and things started to escalate. I really don't remember what was said, but apparently, im a douchebag. That's what a guy said sitting next to me. I mean hell, maybe I was talking down to her, really cant remember the specifics. Anyways, for the sake of reputation how can I mend this over?
