There comes a time in a man's life, if he is unlucky and leads a full life, when he has a secret so dirty that he knows he never will get rid of it. (Shakespeare knew this and tried to say it, but he said it just as badly as anyone ever said it. 'All the perfumes of Arabia' makes you think of all the perfumes of Arabia and nothing more. It is the trouble with all metaphors where human behavior is concerned. People are not ships, chess men, flowers, race horses, oil paintings, bottles of champagne, excrement, musical instruments or anything else but people. Metaphors are all right to give you an idea.)
