"Yeah, that. Like that." That's weirdly relieving. It's not like he ought to have the same emotional reactions as a teenager (young woman, he really doesn't know exactly how old she is), or even a person in general, but it's still kind of comforting that someone else feels the same thing.

He runs through the melody he has so far once more, and now his fingers know it, so it flows easily, like hers did on the guitar. It's only a couple of measures, but it sounds nice. "It's hard to put the right name on something. Sometimes."
