Which was weird, considering he worked in a hospital and all. People were normally at their worst when they were in hospitals. But if he was getting used to her, that was good. It meant that she did not have to be nearly as nice. She thought of it as building up more of his tolerance.

But I can't really be sure." she said with a laugh, looking at him before pushing the door open to the diner and going to sit down. A waitress would be by soon enough after all.
