There is always the risk: something is good and 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 joke around with you anymore, because 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 at the wall of separation between friendship and kissing.
John GreenWhen it comes to girls (and in Colin's case, it so often did), everyone has a type. Colin Singleton's type was not physical but linguistic: he liked Katherines. And not Katies or Kats or Kitties or Cathys or Rynns or Trinas or Kays or Kates or, god forbid, Catherines. K-A-T-H-E-R-I-N-E. He had dated 19 girls. All of them had been named Katherine. And all of them- every single solitary one- had dumped him.
