Mother taught her son to go to the bathroom by the numbers:
1. Open your fly.
2. Take out your equipment.
3. Pull back the skin.
4. Do your business.
5. Let the skin forward.
6. Stow your equipment.
7. Close your fly.
She did check on him often to see if he had learned the lesson, and
heard
1,2,3,4,5,6,7. She was very happy until one day she checked and heard 3-5, 3-5, 3-5.
