The ant story reminded me of the one time DD wrote on the walls, when she was 4. It was a picture of a dog, and the word "NO", on her bedroom door. When we asked her about it, she said it was a note to the dogs to stay out of her room, so they wouldn't chew on her toys. After DW and I had a good laugh at that, we encouraged her to make the sign on paper and tape it to the door instead.

DD, now 8, recently treated DW to a lengthy rant about "Made in China" on all her toys, the gist of which was, "Who cares?"
