The wonders of the Magic Eraser

I just got this e-mail from the wife:

Man, (The Boy) really looks at the world as his canvas. You should see him
looking at the fridge with a crayon in his hand---it really looks like he is
thinking of how to best mark this blank boring canvas. He carefully decides how
to color. Mom reminds him paper only-- Then he turns and looks at the floor.
Wow---this is unmarked too. That boy is stubborn.

Those Magic Erasers are amazing. And expensive. And I'm not going to be getting rid of them any time soon.
