Earthman crash lands on Mars. He wanders around and finds a village. It's fully automated to provide the residents with anything they need. But because it was built by Martians everything is toxic to the human.
The village tries to adapt, but his biochemistry is too alien. Finally, starving, unable to go on, the just lays down in one of the beds and gives up.
When he wakes up, everything has changed. The village smells wonderful, the music sounds great and the bowl of food next to the bed is the best thing he ever ate. The astronaut is so happy that he can't stop wagging all three tails.
