There is always the risk: something is good and good and good, and then all at once it gets awkward. All at once, she sees you looking at her, and then she doesn't want to seem flirty, because she doesn't want you to think she likes you. It's such a disaster, whenever, in the course of human relationships, someone begins to chisel away all the wall of separation between friendship and kissing. Breaking down that wall is the kind of story that might have a happy middle--oh, look, we broke down this wall, I'm going to look at you like a girl and you're going to look like me like a boy and we're going to play a fun game called Can I Put My Hand There What About There What About There. And sometimes that happy middle looks so great that you can convince yourself that it's not the middle but will last forever.
