Setting an example

They're working on some activity sheets for the children's library when I overhear this exchange between Mary and Tina:

"Tina, I don't think we should be using this picture. Don't we have a picture of a burglar who isn't smoking?"

"What for?"

"Well, I don't think it sets a good example to the children."

"So breaking and entering people's houses and stealing things is a good example?"
