One evening on the Vineyard that summer, I guess it was the summer of '66, we were all together at dinner at a mutual friend's house and we got to talking as we did that summer all the time about Vietnam and airing our grievances.  And to my surprise, John didn't have any grievances about Vietnam.  He supported the war in Vietnam.  And we got into an argument.  It was civil.  There was no shouting but it was... it was strenuous and I... look, I was trying to straighten him out.  He was trying to straighten me out.  And what happened is that that dialogue between us turned up in Rabbit Redux and my words are put into... into the mouth of his black hero who's a... who's a kind of revolutionary.  I forget what his name is.  And so, as I was saying earlier, nothing got by him.  Nothing was wasted.  Everything went through... through this transformation and he had this... tremendous fiction-making faculty and he had a sure hand, he... he rarely made a vulgar error.
