He was pleased by the fact that she didn't seem to have the desire to press him for his actual name. He preferred to be called The Doctor, that's what he introduced himself to people as. It wasn't necessary for people to know an actual name, just the name he wished to go by.
"I'm doing great!" he said, enthusiastically. "Lots of new people to meet. It's great. ...especially since I get to meet a beauty such as yourself."
