I met a cute girl at a GSA meetup for the local high schools. I talked to her for a while but I left too abruptly during a game to get her number. She is not on fb and does not go to my school. Any ideas on how to get in contact with someone you met once without being creepy.
Perhaps at the next GSA meet up? Failing that, ask friends if they know her and could put you in touch? If you felt like the feeling was mutual between you, then contacting her through a friend to tell her you enjoyed meeting her and wanted to talk with her again shouldn't come across as creepy at all. She might be flattered you bothered.
