Well, I did have a specific piece in mind, but then started overthinking it (which is sort of the story of my life...)...If last session, he'd just been like, "Sure, go for it," I might have just played it right then, honestly. The main reason I feel it's important is I've come back to the idea of playing music for him a few times over the course of, say, 6 months. I keep thinking about it. So that suggests there's some reason I want to do that, even if it might not turn out to be much of anything.

ETA: I think it was his asking that I print out the lyrics that made me think he might focus on the lyrics quite a bit.
