I just met a cute girl on the subway. I noticed her looking at me so I approached her and we had conversation for about 10 minutes. She seemed a bit nervous, but it was a balanced conversation that went pretty smooth. I asked her out and she said yes. We exchanged numbers and I left. She was actually on her way out of town for a few weeks. If she wasn't , I would call her 3 days to a week later. Now, I don't want to contact her if I can't make plans, but I obviously don't want to wait 3 weeks to contact her. Thanks guys
