In No Exit by Jean-Paul Satre, there are only two other people in the hotel room of garish couches.  Unlike the stereotypical hell, it is not hot in the room and the walls are not red.  The valet who escorts each person into the room is very polite, although a little odd since his eyes do not blink:  "So one has to live with one's eyes open all the time?"  There are no light switches--"life without a break"--no mirrors, so that each person must be reflected in the others' eyes, creating a dependency with people who do not really get along. Each person will act as the torturer of the other:  "Hell is--other people."
