One day a man went home and said to his wife, "I've bought something nice for you." "Thank you!" said his wife. "What have you bought for me?" "I've bought a gold ring. Here it is." He took it out for his wife to see. Then he dropped it to the ground. He began to look for it on the ground, but it was too dark in the house and he could not see anything. Then he went out and began to look for it in the street. Just then a friend came along. "What's the matter with you?" asked his friend. "I am looking for my ring. I lost it in my house." "You lost your ring in your house, but you are looking for it in the street. How foolish it is!" "But it is dark in my house. I shall never find it there. But in the street, it is much brighter, I can see everything."
