“There was something just slightly off in Vince’s bright, Asian smile. Like he had learned to smile from a picture book. Even when he made the required dirty put-down jokes with the cops, nobody got mad at him. Nobody laughed, either, but that didn’t stop him. He kept making all the correct ritual gestures, but he always seemed to be faking. That’s why I liked him, I think. Another guy pretending to be human, just like me.”
