The Boy, Master Communicator

Last night, in the car, just after I picked up The Boy at CCD on my way home from work:

DD: What happened in school today?

TB: Nothing.

DD: Did you have gym or music?

TB: Music.

DD: What did you do in music?

TB: Nothing.

(pause)

TB (earnestly): When I say "nothing," I don't mean we didn't do anything. I just mean I don't want to have a long conversation about it.

Oh.
