Caught white-handed

I was painting our upstairs bathroom the other day when my 4 year old walked in. "Don't touch the walls," I cautioned, "the paint is still wet."

"Okay," he said.

I turned away to apply more paint to the far wall of the room. Then I heard him ask, "What is this stuff all over my hands?" Without looking I asked, "Did you touch the wall?"

"No." A pause. "It looks like paint."

I turned around. Sure enough, it was paint. "Did you touch the paint?" I asked, motioning to the tray I was using with my roller.

"Yeah."

"Well, that's probably where the paint on your hands came from."

He looked at me like I was the wisest person who ever lived. "Oh, yeah!"

We washed his hands and he went on his merry way.
