I live in New York (I'm 18 years old) and I often see a lot of attractive girls on the train or bus and of course the street. While I've already gotten advice on street openers I want to know how to open casually to a girl on the train or bus.
One time i was on the train with a buddy and there was an attractive girl sitting behind him but still kind of facing me. I would laugh and talk to my buddy while giving her quick flashes. Soon she began to look at me more to see if I was looking at her and began to flip her hair. She even began to smile but noticed she was smiling so tried to force herself to stop smiling. Anyway, I knew she was becoming attracted to me but I didn't know how to open to her.
So, what Im trying to say is that I need help opening to girls who show interest in me on the train and bus.
