I was going to say the exact thing. You know talk between a girl and a boy are always sweet nothings. They don't mean anything. And yes this is true. The talk is just to facilitate flow of emotions and that is just what you need to do. Pick up any topic even if it is computers ;P This will stimulate her to pick up her own topics and you can continue. YOu also don't need to be super scientist on the topics she picks up. Just be honest of whatever you say. Pickup mens and womens magzines and learn about a few dating and relationships do's and dont's. One super tip is never let your attention wander away from her when your are talking or you are with her. I guarantee you a successful relationship if you follow this advice.
