A time traveler named Eudoro Acevedo finds himself in an unfamiliar plain—which he asserts looks like all other plains—and walks until he comes across a lighted home. The door is answered by a tall man, and the two sit down together inside. They attempt to speak in multiple different languages before settling on Latin. The man asks Eudoro to eat with him, and the two discuss the world of the future over grapes and cornflakes. The man, who is named “Someone,” and is the son of a nameless man, tells Eudoro that they are accustomed to receiving time travelers. In the future, facts have lost meaning, school teaches students how to forget, rereading is more important than reading, language consists only of quotations, and so on. Money no longer exists, and neither does poverty. The man shows Eudoro around his home; particularly, his paintings, which are large canvases of yellow. Then they are joined by guests, who dismantle the house entirely. Eudoro accompanies the group on a walk to the crematorium, which Someone enters alone with a wave goodbye. Eudoro returns to his own time and hangs one of the yellow paintings up in his study.
