True, Alumnus.
If I like someone I'll contact them too.
Maybe an email instead of phone... Definitely a phone call/message/email after a GOOD date to thank them. If I'm apathetic I won't call.
That said, we girls can get all wrapped up in what we should and should not do as well. "Will he think I'm pushy if I call him?" That kind of thing.
I hate the whole blow off thing--in both directions... I mean if you decide not to move forward, just tell the person, dont disappear.
