 Which term best describes Pop's attitude toward his lunar occupation?
Once in two weeks Earth-time a rocketship came around the horizon from Lunar City with stores for the colony deep underground. When it was first found, scientists descended into it to examine the exposed rock-strata and learn the history of the Moon before its craters were made. Pop lived in it all alone, and in his spare time he worked industriously at recovering some missing portions of his life that Sattell had managed to take away from him. There were air-tight bulkheads for safety, and a hydroponic garden to keep the air fresh, and all sorts of things to make life possible for men under if not on the Moon. In the Moon's slight gravity, a man is really adjusted to existence when he has a well-developed case of agoraphobia. He'd shipped out, whimpering, to the Moon to get far away from Pop, and Pop was just about a mile overhead and there was no way to get around him. There was a warning-bell in the shack, and when a rocketship from Lunar City got above the horizon and could send a tight beam, the gong clanged loudly, and Pop got into a vacuum-suit and went out the air lock. He usually reached the moondozer about the time the ship began to brake for landing, and he watched it come in. Even when Sattell—whimpering—signed up for Lunar City, Pop tracked him. Yet here on the Moon Pop kept a waiting cannister on a shelf in his tiny dome, behind the air-apparatus. The sun rose very, very slowly in what by convention was called the east. Writing-material was scarce, but he spent most of the time between two particular rocket-landings getting down on paper exactly how a child had looked while sleeping, some fifteen years before. Pop Young meticulously touched up the glittering triangles which were landing guides for the Lunar City ships. The occupation made it absurdly easy to live on the surface of the far side of the Moon, whether anybody else could do it or not. Living on the Moon was bad enough anyhow, then, but living one mile underground from Pop Young was much worse. In his mind the need to escape became an obsession on top of the other psychotic states normal to a Moon-colonist. But then an event occurred which bore directly upon Pop Young and Sattell and Pop Young's missing years. Somebody back on Earth promoted a luxury passenger-line of spaceships to ply between Earth and Moon. Workers for the lunar mines could make the trip under heavy sedation.
