Talked to a cute girl from one of my classes, we happened to be in the same place at the same time. Chatted for bit, she put her number in my phone. Didn't text her that night Because some stuff came up but next day I said I would after class. Sent a simple what's up (insert girl name)? it's (my name). Hasn't texted me back yet. It hasn't been a day yet, but if she was interested, wouldn't she have responded by now?
