A traveler walked into a village at night. She was hungry and tired. She knocked on a door.
"I have nothing to give you," said the woman inside. Every door said the same thing.
The traveler went to the village square. She filled a big pot with water. She made a fire. She put a smooth stone in the pot.
A child watched her. "What are you cooking?" the child asked. "Stone soup," said the traveler. "It is good, but a carrot would make it better." A neighbor brought a carrot.
One by one, more neighbors came. One brought an onion. One brought meat. One brought salt. By evening, the whole village ate soup together. It was the stone's soup. But really, it was everyone's.
