When faced with something one has written long ago to have forgotten all about it there seems to be two intuitive responses: embarassment or incomprehension. The first is quite self-explanatory, the second may be an outgrowth of the first: difficult to comprehend that out of the swaths of embarrasing writing one has amassed there are also parts that one need not be ashamed of, parts that therefore seem to break with the essence (or at least repetitive pattern) of one’s writing.
