When our son Stephen was young, he was in Cub Scouts. At each level, I was his Den Leader. After a den meeting one night, he and his friends were running around in the fellowship hall of a church as the adults were cleaning up. The boys were told several times to stop running. Each time they were told to stop running, they were also told that we wanted them to stop running because we were concerned that someone was going to get hurt. Lo and behold, a few minutes later Stephen fell, hit his face on the floor, and broke off the bottom half of a front tooth.
