Im not saying im a complete scumbag but it all depends on what they look like and how well i know them. I have this soft spot for cute girls or close friends but not for fat or ugly chicks. Something similar actually happened to me acouple years ago during my first term in college. A girl who was in my class but i only knew her name never talked to her ran out during a test crying so i handed mine in and went and talked to her to see what was wrong. Turns out she was pregnant and frustrated during the test and the teacher had called her a fat hormonial *****. Turns out he has a very strange sense of humor was only jokeing and trying to get her to relax. Very strange guy, he refers to small children as tax credits aswell.
And i know you said girl but if it was a guy and i knew him i would kick him if not ignore him.
