Yes if he walks over after that it means he thinks your interested and he is interested back. But now I have a question are we guys reading the signs right. I had a girl smile at me and look at me as I passed her. My friend pointed it out. The looking at me was done with my back to her so I couldn't see it. So I walked up to her the next time I saw and started talking to her. So do girls realy like guys when they smile and look at them?
