Last Monday I met a girl through a friend of mine. The 3 of us walked to the store in the snow(took about 3 hours) so we talked a lot and she seemed to show a lot of interest(light kino). When we split ways later I tried to get her to come to my party that night, but she said she already had plans and declined. I said fine, and she left..unfortunately I did not get her number. She did add me on facebook the following day and i'm wondering if I should attempt to set up some sort of date or get her number via facbeook, or wait until me and our mutual friend hang out and she is there.
