[25]Would it be weird if I just gave my number to a boy [22] I was interested at work?He works a different shift than I do, but we see each other pretty much every day in passing. I frequently tell he gets nervous around me, and we lock eyes from across the room a lot. Clearly he is into me.I just don't want to look like a freak for just walking up and saying "here's my number". Have you ever done this?We have talked a little and we pretty much know each others names and that's it.Was planning on giving him my number on a piece of paper, but I don't know. What do you think reddit?
