Personal item: Once I said to a doctor during a “session” that I wished he could get inside my head for just a minute because there’s no way of imagining what this feels like. “Oh, I know,” he said, “I got pretty sad when my father died.”

Defying standard protocol on the couch, I arose on one elbow, turned to him — he was seated behind me — and said, “Do you think grief is even close to this?” To his credit he replied, “I’m sorry. I shouldn’t have said that.”
