There were a lot of mice in a house. The man of the house got a cat. The cat killed many of the mice. Then the oldest mouse said:"All mice must come to my hole tonight, and we will think what we can do about this cat."
All the mice came. Many mice spoke , but none knew what to do. At last a young mouse stood up and said:" We must put a bell on the cat. Then , when the cat comes near, we'll hear the bell and run away and hide. So the cat will never catch any more mice."
Then the old mouse asked :" Who will put the bell on the cat?" No mouse answered. He waited, but still no one answered. At last he said:"It is not hard to say things, but it is harder to do them."
