Today was the day Little Brother and I volunteer in the school lunchroom. There's one little boy in first grade who asks, every day, for a "metal spoon" (come on, Mom, give the kid a spoon for his yogurt!) It's got to be metal, too, not plastic. So we just tell him to bring it back when he's done.
He comes back to return the spoon, wiping it off on a paper towel. Then he says, "If I wipe off the spoon real good, do I have to give it back?"
