One day when my kids were much younger, my youngest daughter, Mary was arguing with her brother, James, in our kitchen. I don’t remember how old she was but if she was school age, she hadn’t been in school very long. She got mad enough to tell him, “James, you’re an asshole!” My wife was in the kitchen with them and asked Mary, “What did you say?” Mary replied, “I called him an asshole!” My wife told her, “you aren’t supposed to say that.” Her response was “Oh!” Like she had never considered calling him anything else. There has been much finger-pointing and speculation about where she heard this language.
