Last night at a bar I was introduced to a lovely lady by the bar owner (whom I have known for some time; we are not good friends or anything, just used to work together several years ago). After striking up conversation with her and getting some good body language indicators (no kino, however), I did manage to get her number and confirm it was hers when she got my phone call (I personally always call the number while I get digits just to make sure it goes to their phone, personally).

Anyway, said goodbye after a bit, and this morning I sent a text "It was nice meeting you last night; hope to see you soon :)" at around noon and haven't received a reply. I guess my question is, what is the amount of time I need to give her before deleting her number and shelving this experience among the list of many tried but failed attempts?
