Elevator surprise

Taking the elevator to my office, a gentleman gets on, probably faculty, just the two of us ... he sees my Ukulele Underground hat, which I recently bought, and says, I'm learning the ukulele. I recommend UU very highly. I ask if he plays another instrument. Banjo, in the clawhammer style. I do, too, I say. Clawhammer uke is great! And the door opens, and we go off in opposite directions, grinning.
