Parental Supervision?

3rd grade boy: "Mrs. Clamforest, I have a present for you! It's my lucky penny!"

Me: "That's very sweet of you, but you don't need to give me your lucky penny; it must be very special!"

Boy: "Yep, it is! I found it stuck in the bottom of our lawnmower! You can have it though, I don't mind!"
