One time I was in the kitchen drinking tea with my husband and our young son, and they got into an argument about ice hockey. I do not feel passionate about ice hockey. They do. Finally our son said. “But Daddy, you don’t understand.” And my husband said, reasonably, “It’s not that I don’t understand, Bion. It’s just that I don’t agree with you.”

To which the little boy replied hotly, “If you don’t agree with me, you don’t understand.”

I think we all feel that way, but it takes a child to admit it.
