There are almost no characters in this story, and almost no dramatic confrontations, because most of the people in it are so sick and so much the listless playthings of enormous forces. One of the main effects of war, after all, is that people are discouraged from being characters.

"The letter said that they were two feet high, and green, and shaped like plumber's friends. Their suction cups were on the ground, and their shafts, which were extremely flexible, usually pointed to the sky. At the top of each shaft was a little hand with a green eye in its palm. The creatures were friendly, and they could see in four dimensions. They pitied Earthlings for being able to see only three. They had many wonderful things to teach Earthlings, especially about time. Billy promised to tell what some of those wonderful things were in his next letter.
Billy was working on his second letter when the first letter was published. The second letter started out like this:
The most important thing I learned on Tralfamadore was that when a person dies he only appears to die. He is still very much alive in the past, so it is very silly for people to cry at his funeral. All moments, past, present and future, always have existed, always will exist. The Tralfamadorians can look at all the different moments just that way we can look at a stretch of the Rocky Mountains, for instance. They can see how permanent all the moments are, and they can look at any moment that interests them. It is just an illusion we have here on Earth that one moment follows another one, like beads on a string, and that once a moment is gone it is gone forever.
When a Tralfamadorian sees a corpse, all he thinks is that the dead person is in a bad condition in that particular moment, but that the same person is just fine in plenty of other moments. Now, when I myself hear that somebody is dead, I simply shrug and say what the Tralfamadorians say about dead people, which is "so it goes.

"It was not the thought that I was so unloved that froze me. I had taught myself to do without love.
It was not the thought that God was cruel that froze me. I had taught myself never to expect anything from Him.
What froze me was the fact that I had absolutely no reason to move in any direction. What had made me move through so many dead and pointless years was curiosity.
Now even that had flickered out.
How long I stood frozen there, I cannot say. If I was ever going to move again, someone else was going to have to furnish the reason for moving.
Somebody did.
A policeman watched me for a while, and then he came over to me, and he said, "You alright?"
Yes," I said.
You've been standing here a long time," he said.
I know," I said.
You waiting for somebody?" he said.
No," I said.
Better move on, don't you think?" he said.
Yes, sir," I said.
And I moved on.
