as collide said, forget to call is pretty bad. ie you mean nothing to me. Also its very hard for a guy to call a girl he's interested in cause you get so nervous, especially when you have just meet them, and you ahve in your head that you don't want to come across as some dick. Although you do come across as a dick if you put off calling her.
It might come down to the mind games people play in realtionships to get more "hand" so to speak. I don't know, someone always wants to think of themselves on top.
And Averett, i hope that guy calls you soon. If not, give me your number and i'll call you
smooth.... i know :P
