Describe the relationship between Hollis and Lespere.

After their rocket was cut "up the side" as though it was cut "with a giant can opener," the men inside are cast out into the universe in different directions, doomed to float through space until they die. As the astronauts drift farther and farther away from one another, some of them speak to each other. Some men panic and say upsetting things or just scream, but Hollis considers his feelings about the others. He "wanted more than anything at this moment to be able to do something to Applegate," and Applegate expresses his own hatred of Hollis. Applegate tells Hollis that he'd had Hollis blackballed from some organization to which they'd both belonged years ago—it's mean of him. Then, the narrator says,

That one man, Lespere, went on and on with his talk about his wife on Mars, his wife on Venus, his wife on Jupiter, his money, his wondrous times, his drunkenness, his gambling, his happiness. On and on, while they all fell. Lespere reminisced on the past, happy, while he fell to his death.

Lespere talks about what a "'good time'" he had in his life: a wife on each planet, plenty of money, and so on. At first, Hollis thinks that, though he had none of these things and actually used to envy Lespere, they are equal; they both ended up here, in the same place. However, he feels like being mean now, and he acts on it, telling Lespere that "It's all over" and that "It's just as if it never was." Applegate hurt Hollis, and now Hollis wants to hurt someone else; having resented Lespere for so long, perhaps he seemed like the best choice.
Lespere says that he is still better off than Hollis—even now—because he has his good memories, while Hollis only has unfulfilled dreams. In the end, Lespere says that he is "resting easy" because he's "had [his] turn" and isn't "'getting mean'" in the end. Hollis realizes that he's "been as good as dead for many years" while Lespere was enjoying a "good full life." In the end, listening to Hollis be mean compels Applegate to repent and take back what he said. Hollis envied Lespere's good fortune, and, made to feel victimized by Applegate, Hollis decides to try to make Lespere his victim, but it does not work because Lespere is satisfied with himself and his life.

The short story collection The Illustrated Man by Ray Bradbury contains 18 tales, the second of which is "Kaleidoscope." The story describes the final moments of the lives of the crew of a spaceship that is drifting through space when their equipment fails. Each astronaut's final thoughts and feelings are shared as they head toward certain death.
Hollis and Lespere are two of the crew members nearing the end of their lives. Hollis is plagued with regret and anger, unable to deal with the reality that he will be burned up upon entering the Earth's atmosphere. Lespere, on the other hand, spends his last moments reminiscing about the full life he led. He is happy and found love and meaning in his life.
Hollis becomes frustrated with the idealistic portrait of life that Lespere paints, but despite Hollis's protests, Lespere holds strong. He does not want to be mean and angry at the end—the way that Hollis is. The truth is that Hollis is jealous that Lespere lived his life rather than simply dreaming it.
