I have a pretty social career and am fairly personalble so I meet quite a lot of different people at bars/restaurants/clubs/etc. The last 6+ times that I can recall I've met a girl and talked/etc, grabbed their number at the end of the night, and sent them a text later, I've never received a reply. Usually I just send some version of "hey it's (my name)" and maybe a "nice to meet you (when/where we met)" and typically will do that within a day. Or sometimes a cheeky follow up to some part of the conversation we were having. Am I missing something?
