question:  Why does no one on town know who Haron Gorka is?
context: She had been known to say that there are over a billion men in the world, a goodly percentage of whom are eligible bachelors, and that the right one would come along simply because she had been waiting for him. Intelligent, somewhat egotistical male who's really been around, whose universal experience can make the average cosmopolite look like a provincial hick, is in need of several female correspondents: must be intelligent, have gumption, be capable of listening to male who has a lot to say and wants to say it. The name—Haron Gorka: its oddness was somehow beautiful to Matilda. Haron Gorka—the nationality could be anything. He had no nationality for all intents and purposes; he was an international man, a figure among figures, a paragon.... Matilda asked him where she could find Haron Gorka. "I said, where can I find Haron Gorka?" First place, I don't know any Haron Gorka—" Matilda kept the alarm from creeping into her voice. Matilda did, only they didn't know any Haron Gorka, either. As far us the gentry of Cedar Falls was concerned, Haron Gorka did not exist. If she could not find Haron Gorka, that was one thing; but she knew that she'd rather not return home and face the widow Penshaws, at least not for a while yet. Twenty years from now, this could be Matilda Penshaws—complete with plain gray dress, rimless spectacles, gray hair, suspicious eyes, and a broom-stick figure.... Certainly a man as well-educated as Haron Gorka would be an avid reader, and unless he had a permanent residence here in Cedar Palls, one couldn't expect that he'd have his own library with him. This being the case, a third-rate collection of books was far better than no collection at all, and perhaps the librarian would know Mr. Haron Gorka. "I'm looking for—" "Haron Gorka." I never did trust this Mr. Gorka...."
output:  He’s not a real resident, but an interstellar visitor.
options:  Haron Gorka isn’t his real name. Thus, there’s no records of him.  He’s not a real resident. He’s using a fake name while he stays in town.  He travels so much that the people in town haven’t gotten to know him.  He’s not a real resident, but an interstellar visitor.
