Tonight eight-year old Kailee came to me with a piece of paper. It was a sign-in form for her club, and she wanted to know if she could copy it five times so that she could give one to each of her neighborhood friends. I said sure, thinking she meant could she have some more paper or take the time to hand-copy them.

When I went upstairs a few minutes later, I found her at the fax machine. She had meant could she copy the page using the fax machine. And not only that, she knew how to do it on her own. That'll teach me to blindly say "sure" without further inquiry.
