Well, if that was how you started then that's definately kinda creepy. You gotta get to know a person before you ask if they wanna do something with you. Even if getting to know them is like, a 5 minute chat that started for a reason. If the first thing that came out of your mouth was "What are you doing this evening", she was most likely intimidated. If it's going to haunt you, go ahead and say sorry if I came on a little strong the other day or something like that. -laughs- I don't know. Otherwise if it's not going to bother you, just leave it as is. There are lots of nice girls out there. Just take it as a learning experience and pick another nice girl. :S If you really want this nice girl, apologize for coming on too strong and try a different tactic. Maybe wait until you've talked a few times ((keep it light)) and ask for her email or something.

I was just in a similar situation, I came on too strong ((via email)) and she backed off. Her last email to me was "Sorry, been very busy." I just moved on.
