I suck with girls so I still don't know what to do with this. I've never gotten eye contact and a smile in bar/party situations, but I always get it from daily life and I don't know what it means (i.e. getting on a bus, etc.). Just today I was walking home and a girl was moving into her new apartment and I made eye contact and smiled. I was going to ask if she needed help but then I thought maybe she was just being friendly and not interested. What exactly does eye contact and a smile mean?
