If you know the Refreshments...their song "Banditos" comes to mind...part of the chorus being "the world is full of stupid people."

It's amazing to me how so many people with children, upon becoming parents and loving someone unconditionally probably for the first time in their lives, forget that not everyone or everything in the world around them is "child friendly." I agree with letting children be children and learning from their mistakes, but not when it's a possibility that a mistake could be permanently damaging or even fatal. There should be leash laws for some parents and their children.
