Poor Form

I think it's poor form when a guy doesn't contact a girl after they "hang out."  Was talking to some guys and gals about this.  The general consensus - guy should contact the girl, even if they met outside a bar at 2am and it was a one nighter.

What possesses a guy to think it's okay not to contact her?  If anything, wouldn't a guy want to because he could hope to set up a steady 2 am "friend?"  (I am not talking about me.) 

Yeah yeah, I understand guys can be scared of rejection, etc., but come on.  Yeah, the girl could reach out to the guy, but really, man up!
