I’ve long been interested in the topic of how children resolve disputes, a fascination that dates back at least to an incident in third grade when Randy McMillan and I had a disagreement over which of us should get to play pitcher in a game of kickball at recess. After a brief discussion of the salient points, Randy and I eventually arrived at a compromise, agreeing that because he was bigger and stronger, he should probably pitch, and because I was smaller and weaker, I should probably shut up if I wanted to keep all my teeth. Handing over my lunch money might also be wise, he helpfully added.
