My son the shoplifter

I'm ashamed to admit it, but we have a shoplifter in the house. Andy has such quick little hands these days that I'm finding after I leave a store that we've accidentally taken something we weren't supposed to. So far, he's stolen a $.99 plastic Monster truck and an $.83 pack of Crayons, both from Target and on separate days. Today at Wegman's, I had just paid when I realized he was hoarding some Cabot cheese in his hands. I was still at the register, but we'd just paid so I had to fork over the $2.05 in cash. Fortunately, I caught it this time before we were in parking lot.
