Each day, when I would come home from work, I would drop to my knees and ask my four-year-old son if he wanted to box. I wanted him to learn how to protect himself. We would spar around for a few minutes before supper.

One day, my wife and I took our son to get new shoes. The shoe salesman was friendly and allowed my son to try on several pairs of shoes before we decided on a particular pair that he liked. We asked if he wanted to wear them home and he replied, "Yes!"

The salesman, who was kneeling on the floor in front of our son, held the old shoes in his hands and asked, "Do you want a box"?
