An autobiography is a book a person writes about his own life and it is usually full of all sorts of boring details.
This is not an autobiography. I would never write a history of myself. On the other hand, throughout my young days at school and just afterwards a number of things happened to me that I have never forgotten.
None of these things is important, but each of them made such a tremendous impression on me that I have never been able to get them out of my mind. Each of them, even after a lapse of fifty and sometimes sixty years, has remained seared on my memory.
I didn’t have to search for any of them. All I had to do was skim them off the top of my consciousness and write them down.
Some are funny. Some are painful. Some are unpleasant. I suppose that is why I have always remembered them so vividly. All are true.
