<human>: I left my number on a girl from class's car.  We talked everyday and flirt and I asked her out when we were talking.  I asked if she wanted to go out sometime and she said yes.  I asked for this weekend and she gave a legitimate reason for being busy.  How long should I wait and what should I say/do when making a second attempt?  I am thinking I will call and ask her to something casual.  There is a pro basketball game this next week that she is a fan of one team and I am a fan of the other.  Is that too big of a first date? Just looking for a little advice so I'll take what I can get.

Can you provide a brief overview of the text?
