Who's Going to Hang the Bell?
One day the mice who were really scared of the cat gathered around and had a meeting. The first mouse
said, " More and more mice are killed by the cat these days. Do you have any idea to stop that? " The second
mouse said, " Alas, we cannot live one day without fear. We'll die soon."
So the mice tried to think of a way not to be caught by the cat." I have an idea. How about all of us
jumping at him together." " Hmm, that's silly. How can we beat the cat? We shouldn't dream to fight him.
Instead, let's think a way to know if he's coming." The mice tried and tried to think it up.
Then a mouse who kept quiet said, " How about hanging a bell to the cat's neck? " " Wow, that's a good
idea. So we can run away when the bell rings." They all clapped with joy.
Then the oldest mouse said, " That's a very good idea, but who's going to hang the bell around the cat's
neck? " The mice just looked at each other's face, and one by one hung back to the mouse hole.
