So there really are teachers who live at school? I knew it. [Said in the tone of a child who's just had a very important life fact confirmed for him, because that's definitely what he should be focusing on right now.

Picking up one of the piles of books, he carries them over to the appropriate subject shelf. Carrying all of them at once has made him a little wobbly, but he's very determined to get them over there.]

Are you cleaning stuff up? I dunno if you could use some of the classrooms I saw earlier. [Finally reaching the appropriate shelf, he drops the books there and starts to stand them upright properly.]
