Don't feel bad, Forrest. I didn't think your actions were all that creepy, given this brave new age, and your crush's response suggests she didn't think they were, either. Now all you have to do is suggest that you share some safe, pleasant activity (I have no idea what counts as suitable for first meetings; hell, I don't think I've been on a date in my life), and bob's your uncle. Or not, if one or the other of you discovers that what you liked for a few moments of flirting doesn't support further congress. But you can deal with that when the time comes.
P.S. Next time you want to be anonymous, you'll be more careful to cover your tracks, so there's a useful lesson learned.
