My FIL taught my DS, when at the farm, that if you had to pee you just went where you were. So in town when he was out playing he would just go in the yard. Got him broke of that, then started peeing out his bedroom window. The urine stains on the house were a dead giveaway.
I does get worse. There's the jumping off the garage roof, the broken windows, the hill jumping with his bike, the concussions, the knocked out teeth, etc, etc, and so on. All this goes on until they get their drivers license....
