There were many 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（洞）tonight, and we will think what we call do about this cat.”All the mice came and many mice spoke, but none know 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 shall hear the bell and run away and hide. So the cat won't catch any more mice.”Then the old mouse said,“Who will put the bell on the cat?”No mouse answered. He waited, but still no one answered. At last he said,“It's not hard to say things but it's hard to do them.”
