A primeira história soa como "Ontem foi segunda", uma breve história de Theodore Sturgeon, que também foi a resposta para essa velha pergunta (entre outras) Foi publicado pela primeira vez em Ficção de fantasia desconhecida, Junho 1941, disponível no Internet Archive.
Harry sat down on a grease drum and wrinkled up his brains with the effort he was making. "You mean that this time proposition ain't something that moves along? Sorta—well, like a road. A road don't go no place—You just go places along it. Is that it?"
"That's the general idea. In fact, that's a pretty good example. Suppose we say that it's a road; a highway built of paving blocks. Each block is a day; the actors move along it, and go through day after day. And our job here—mine and the little men—is to . . . well, pave that road. This is the clean-up gang here. They are fixing up the last little details, so that everything will be ready for the actors."
A segunda história foi identificado em Resposta de Mark Mills as "Um dia comum, com amendoins", uma breve história de Shirley Jackson. Foi publicado pela primeira vez em A Revista de Fantasia e Ficção CientíficaJaneiro 1955, disponível no Internet Archive. No trecho a seguir, o Sr. Johnson acabou de chegar em casa depois de passar o dia sendo agradável e gentil com as pessoas:
Mrs. Johnson came out of the kitchen and kissed him; she was a comfortable woman, and smiling as Mr. Johnson smiled. "Hard day?" she asked.
[. . . .]
"I didn't do so badly," Mr. Johnson said. "Couple young people."
"Fine," she said. "I had a little nap this afternoon, took it easy most of the day. Went into a department store this morning and accused the woman next to me of shoplifting, and had the store detective pick her up. Sent three dogs to the pound—you know, the usual thing. Oh, and listen," she added, remembering.
"What?" asked Mr. Johnson.
"Well," she said, "I got onto a bus and asked the driver for a transfer, and when he helped someone else first I said that he was impertinent, and quarreled with him. And then I said why wasn't he in the army, and I said it loud enough for everyone to hear, and I took his number and I turned in a complaint. Probably got him fired."
"Fine," said Mr. Johnson. "But you do look tired. Want to change over tomorrow?"
"I would like to," she said. "I could do with a change."
