One day a mouse was looking for something to eat. Suddenly he ran into a lion. The lion caught the mouse. He looked at the mouse and said, "You're too small for a meal. "
"Please let me go, Mr. Lion," said the mouse. "One day I will help you. " The lion laughed. "How can a little thing like you help the great king of animals?" he said. "OK, I will let you go. ""Thank you very much," the mouse said. "That's very good of you. "
The next week the mouse was again looking for something to eat. He saw the lion under a tree. The lion was in a net and could not get out. The mouse went up to him. "Don't worry, Mr. Lion. I will help you," said the mouse. Then he began to bite the net. Soon he made a big hole in the net. At last the lion got out of the net. He was very happy. "Thank you," he said. "Thank you so much!"
