It must have been after some intense discussion, not an argument, nothing personal, just my usual gloom erupting, that Catherine wrote in pencil on a sheet of "While You Were Out" paper that I came across in a pile of papers months later, long after I'd forgotten what we might have been disagreeing about: "Differ without rancor as a man may differ with himself..."
I have no idea where she found the quote, but underneath it, in blue ink in my hand, is written: "I differ from myself with rancor."
Then in pencil under that, in her writing again, "You're stupid, that's why."
