I am taking defensive driving-classes after school twice a week, and there is this shy girl that I have noticed looking at me. We have only talked about three times, and I want to talk more and get her number before the classes are over. The class instructor had told me that her mom had said she could see me with her daughter, but I am still not able to approach her. I think that would mean that her mom would be okay with it, but her Dad is also there and I don't know how to flirt if parents are around. How can I approach her, and how can I eventually get her number?
