So there is this girl at my work I've been talking to for a few weeks. I talk to her probably once every three days or so. Now this girl has a boyfriend so I'm not sure if she will get the wrong idea. I was thinking of just lightly hitting her on the shoulder when I walk by and just saying hi to her as I walk by. Sometimes she's with a customer and I'll pass by her. This is just to be more friendly with her. Are there other things I can do?
