My wife always hears the best (and most bizarre) conversations. Take yesterday's at a neighborhood park as she was watching nephew number three.
Young girl to nephew number three: "Grrrrrrr."
Mom: "Do we have to leave? I've told you before to stop growling at people."
Hmm. If at six years old your child growls at strangers, you as a parent just might have an interesting road ahead of you.
