mountains. Suddenly she saw something shining(发光) in
the stream. When she came close, she found it was a precious(宝贵) 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.”
The woman opened her bag. It was almost empty. She
looked at the young man and smiled, “I have nothing special in my bag, but I do
have something precious — the joy of giving!”
The young man felt ashamed(羞愧) and left silently.
