disturbing imaginations

While I was sorting laundry a few minutes ago, I heard Joshua and Patience playing. They were pretending their stuffed animals were a family of lions. The kid lions asked if they could go to the playground. The response was, "You are old enough to go to the playground by yourself. Just..." I was expecting some typical parental advice like "be careful" or "don't talk to strangers." Instead the end of the sentence was "eat anybody who is mean to you."
