 How does the format of the story supplement the character?
A Gleeb for Earth By CHARLES SHAFHAUSER Illustrated by EMSH [Transcriber's Note: This etext was produced from Galaxy Science Fiction May 1953. 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. I have attuned myself to a fetus within the body of a not-woman in the not-world. My wave went out to yours and found it, barely pulsing and surrounded with an impregnable chimera. 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. I must leave off now because the not-child is about to be born. When it is alone in the room, it will be spirited away and I will spring from the pod on the gateway into its crib and will be its exact vibrational likeness. This is the only way I could arrive in the room where the gateway lies without arousing suspicion. I will grow up as the not-child in order that I might destroy the not-people completely. All is well, only they shot this information file into my matrix too fast. 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. He was out on ... what did they call it? He did not arrive till three days after I was born. This was the first use I had made of the so-called vocal cords that are now part of my extended matrix. They apprehended him on the stairs and I heard him babble something about my being a monster and no child of his. My not-mother appeared at the doorway and instead of being pleased at the progress of my growth, she fell down heavily. 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.
 Each letter comes from a different location, lending credence to this character's story.
 Each letter comes from a different location, lending credence to this character's story.  It proves that Glmpauszn is lying.  The way the letters are presented makes the speaker seem unreliable.  The way information is presented allows the reader to infer their own judgements of the character,
