That's How I Roll

Charissa, 10, slogs through a piece she hasn't practiced recently.

Me: You are so brave to stick it out through such a tough piece!  And don't feel badly; I know you didn't play as well as you would have liked, but all the basics were there.  It's just a little . . .

Charissa: Rusty?

Me: Yes, that's exactly what I was going to say.  How did you know?

Charissa: Well, that's pretty much your favorite term.
