Overheard

Benny (after giving Andy a freshly-sharpened pencil): And you can take it to school!
Andy (to me): If we need to, we can use it for math. If we need to.
Me: If we need to.
Benny (with his hand on Andy's shoulder): Andy, kindergarten does not have math. I know.

A little later...
Benny: Andy, your work might be a little sloppy, but that's okay, right?
Andy: Right.
