Joshua, as your sister may tell you too, sometimes us girls will drop hints about things we want to do, or would like to talk about hoping the guy will pick up on it. Example, I say "I really like ice cream cones" in front of Jake when we are at the park, and he would pick up on it and say "let's hit Dairy Queen on the way home". But you will get used to this as you get older and figure it out. You can always ask her too, us girls do not get offended. And sometimes we change the topic in front of a guy because we think we are boring him. So keep her interest no matter what you are talking about with her.
