question:  Why might the stories be true?
context: Extensive research did not uncover any evidence that the U.S. copyright on this publication was renewed.] Not to be or not to not be ... that was the not-question for the invader of the not-world. India, China, England, everywhere. Hold firm in your wretched projection, for tomorrow you will not be alone in the not-world. I have attuned myself to a fetus within the body of a not-woman in the not-world. So I must communicate with you by what the not-world calls "mail" till we meet. I, Glmpauszn, come equipped with powers evolved from your fragmentary reports before you ceased to vibrate to us and with a vast treasury of facts from indirect sources. He does not know he writes it. You must never know of my exact location, for the not-people might have access to the information. I must leave off now because the not-child is about to be born. But the not-people must never know I am among them. I will grow up as the not-child in order that I might destroy the not-people completely. There is no way of describing to you in not-language what I had to go through during the first moments of my birth. I learned the following day that the opposite component of my not-mother, my not-father, had been away riding on some conveyance during my birth. They apprehended him on the stairs and I heard him babble something about my being a monster and no child of his. From now on I will refer to not-people simply as people, dropping the qualifying preface except where comparisons must be made between this alleged world and our own. It is merely an offshoot of our primitive mythology when this was considered a spirit world, just as these people refer to our world as never-never land and other anomalies. Anyway, I shall carry on swiftly now to the inevitable climax in which I singlehanded will obliterate the terror of the not-world and return to our world a hero.
