Ultimately you don’t know if she’s a bitch or a normally cool person protecting herself/sick of guys hitting on her/in a bad mood. It’s fine to give it a minute to see if she’ll come around (demonstrate that you’re way cooler/more interesting than the vagrants who have been trying to chat her up all night), but then leave. I’ve had people who started out cold warm up to me pretty quickly–but like Ryan’s saying, some girls are just flat-out losers. Weed them out.
