You live with your wife and children on a farm outside of a small rural town. You son John is 12 and helps with chores around the farm. On the farm you grow some vegetables for your own use, but the main income is breeding and boarding horses. Everyone in the family knows that it is important to keep the paddock gates closed so that the horses can't get out. Right after breakfast, John was rushing to go to a friends house, and left one of the gates open. One of the mares got out of the paddock, and to make things more serious, managed to get into the sweet feed. She ate way too much feed and you thought you were going to loose her. You were able to walk her enough to prevent colic but you had to drop everything else and deal with her all day. It is now dinner time, and John is just getting back to the farm.
What are you going to do?
