I am forever your debtor for reminding me of that curious passage in my life. During the first year or two after it happened, I could not bear to think of it. My pain and shame were so intense, and my sense of having been an imbecile so settled, established and confirmed, that I drove the episode entirely from my mind - and so all these twenty-eight or twenty-nine years I have lived in the conviction that my performance of that time was coarse, vulgar, and destitute of humor.
