What kind of rules should govern our lives? I’d argue that the best rules are those that we’d be satisfied with if our very worst enemy were in charge of decision-making. The foundation for such rules was laid out by my mother. Let’s look at it.

My mother worked as a domestic servant. That meant that my younger sister and I often lunched at home by ourselves during our preteen years. Being bigger and stronger than my sister, I seldom divided the food evenly, especially the desserts. After a tiring day at work, Mom would be greeted by sob stories from my sister about my lunchtime injustices. Mom finally became fed up with the sibling hassles. She didn’t admonish me to be more caring, fair, sensitive and considerate. She just made a rule: Whoever cuts the cake (pie, bread, meat, etc.) allows the other the first selection. With that new rule in place, you can bet that when either my sister or I divided food, it was divided equally.
