If a girl gave a number to a guy (he really really asked for it on a birthday party of a mutual friend on which they spend great time dancing/talking) and he is not calling for 1 week, 2 weeks..
Well my question is when do you know that the guy will NOT call at all (don't even expect).. IF you know HIS friend when is it OK or not to kind of double check what's going on on the other end?..
Basically what's the ethiquete? THANKS!
