W. B. Yeats 
Reveries over Childhood and Youth 

Sometimes when I remember a relative that I have been fond of, or a strange incident of the past, I wander here and there till I have somebody to talk to. Presently I notice that my listener is bored; but now that I have written it out, I may even begin to forget it all. In any case, because one can always close a book, my friend need not be bored.
I have changed nothing to my knowledge, and yet it must be that I have changed many things without my knowledge, for I am writing after so many years, and have consulted neither friend nor letter nor old newspaper and describe what comes oftenest into my memory.
I say this fearing that some surviving friend of my youth may remember something in a different shape and be offended with my book.
