My wife and I decided that our children were getting old enough to leave them home alone for short periods of time, so we thought that a fifteen-minute walk down our country gravel road would be a good place to start. We told our children, “You have one job—safety! Make sure everyone is safe.” It seemed simple enough, and we thought, “What can go wrong in fifteen minutes when we are only a couple blocks away?” Turns out, a lot can go wrong. When we turned into the driveway at the conclusion of the walk, our son came bursting out the back door, screaming at the top of his lungs, holding a rag over his mouth. When he removed the rag, tooth chunks fell to the ground.
