One of our unnamed children was obsessed with fairness. If we did something she considered unjust, we would regularly hear, “That’s not fair”. It often came out when something happened and no one would confess or tell on each other so we would administer justice to all of them. It usually involved some form of group activity like having to pick up dog mess in the yard or not getting to watch TV or a loss of a reward like ice cream. The concept of fairness is one we all desire.
