One of my son's for some strange reason has the habit of biting his hand when angry. Some "doo-gooder" at school reported that the blisters on his hand were cigarette burns...The only problem is neither I nor my wife smoke. Sure enough child welfare was out here on the complaint. They bipassed my wife and immediately start running a gestapo-type do on me. Yes this is in America. I had another son who did the sliding down the pole on the slide bit...upside down. Didn't think about the cement anchors at the bottom of the pole. He cut his nose pretty good. Lucky he didn't break it. The gestapo was out again the second time and there were even other kids saying what my son did. But they give you that look. You're guilty! It doesn't matter what the facts are. I suppose I could follow him around making sure that stuff didn't happen, but then there's the neighbor who insists I'm stalking kids when I do.
