"I don't think Nixon has a friend. I've known him for a long time. I've interviewed him many times, in one of which, at the very end of the interview, I asked him, 'Mr. Nixon, can you ever relax with anyone?' And he said—it was rather pathetic, to me, Dick—he said, 'No, I never can. I can never really let my hair down with anybody.' And then I said, 'Not even with Pat?' And he thought for a moment and he said, 'No, not even with Pat.'""
