I think the first thing author Steve Brust ever said to me was "Let's have an argument. Roger Zelazny's Lord of Light [my link -C] is the best book anyone's ever written."
"Ah," I said, "If you make it best SF book of the 1960s, I'll go along with it."
"Oh. Fair enough."
It was the first of a long line of failed arguments.
