There's this girl I work with and we kind of just talk about whatever but it seems like there might be some chemistry. I have her added on social media and would like to talk to her more but: 1. We both get busy at work and may see each other once per shift. 2. I don't want to be to forward so I've been taking my time making certain advances. Basically, should I just keep up with the in person conversation until things grow or maybe send a message?
