I've always had trouble picking up on ques as to if a girl is flirting or just being friendly. This girl I work with has commented on my beard, asked if I was married, stolen my pen, asked if I had OCD based on something I did (not in a mean way, I wasn't offended), said maybe I wasn't married b/c I was too picky (again not in a mean way), and we have joked around quite a bit. She is pretty outgoing so I sometimes get that confused with being flirty. Obviously all these things have occurred over a period of time.
