I'll tell you guys a story. When my son was 14, he always took the dog on the 4 wheeler for rides. The dog loved riding and he rode on the seat in front of my son.
One day, they were riding across the field toward where I was working. A possum ran by and the dog suddenly jumped out. From my perspective, it looked like the dog jumped right in front of the 4 wheeler. I was thinking my son would run over the dog --- and believe me, that would have been a disater of biblical consequences (for the whole family but especially my son).
Anyway, he just missed the dog and all was good. From that day on, the dog was not allowed on the 4 wheeler. I didn't even have to say a word - my son knew.
