Hey Doc, I'm 17, and today the most amazing girl struck up conversation with me, albeit somewhat brief. We have a class together, but I saw a side of me I'd never seen before...a confident streak. I've never been with anyone, but, I wanna keep talking to her, maybe so that such becomes possible?
It's called chemistry. She obviously talked to you in a way that made you feel very comfortable. That's what gave you the confidence. Keep talking to her, but don't go overboard. Being too over the top will turn her off. Just play it slowly but confidently and see what happens. There are no guarantees, but it sounds like this is a good start.
