Let's say you approach a girl on the street, you chat for a bit, perhaps she's in a rush, so you take her number and say you want to go on a date with her. She agrees to give you the number, or maybe she makes up some excuse at first. You easily just brush that excuse off and she gives you her number. You text her maybe in an hour, or maybe right after that, or maybe in a couple of hours. Whatever the case is, you text her. And by the end of the day, she doesn't reply at all. What is the proper way to handle this situation? Text again? Don't text at all and consider it done? Looking for credible advice.
