Let's think about them. For me a major deal breaker is if a guy says something racist or homophobic. One night this guy was trying to pick me up and doing a pretty damn good job for someone shorter than me and not as conventionally attractive. He was smart and funny, I noticed his attempt at a neg and let it slide because he knew a few obscure authors and could read me like a book. Would have definitely given him my number, probably would have let him kiss me if he dared. But then he goes and talks about how all these gay men have been hitting on him lately and how gross he thinks gay guys are and how it bothers him when they hold hands in public. Wrote him off instantly.

I know other girls who will write men off if they're wearing the wrong kinds of pants or wear shirts with logos.

What makes you write potential partners off?
