     One day an old woman was traveling alone in the mountains. Suddenly she saw something shining in the

stream. When she came close, she found it was a precious stone. She put the stone into her bag and went on

with her trip.

     The next day the old woman met a young man, who was also a traveler in the mountains. The young man

looked very hungry, so the old woman opened her bag to share her food. The hungry traveler saw the precious

stone and asked carefully, "The stone is beautiful. Would you like to give it to me?"

     "Sure. Why not?" the woman said, and handed the stone to him.

     The young man left happily with the stone. He knew it was worth enough to give him security for a lifetime.

But a few days later he came back to return the stone to the woman.

     "I've been thinking," he said. "I know how valuable the stone is, but I give it back and hope that you can give

me something even more precious. Give me what you have within your bag."

special in my bag, but I do have something precious-the joy of giving!"
