My favorite story

The first point of view of the young mouse: Recently, there is a big cat in the house, who caught many companions of us while we were stealing food. One day, we had a meeting to talk about the way to deal with our common enemy. Some said this, and some said that. At last I got up, and said that I had a good idea. "We could tie a bell around the neck of the cat. Then when he comes near, we can hear the sound of the bell, and run away." Everyone approved of this proposal, but an old wise mouse got up and said,"That is all very well, but who will tie the bell to the cat?" We looked at each other, but nobody spoke.
