Write a story that illustrate the saying: '' prevention is better than cure.

There is an old story in which there lived three fishes in a pond which was connected to the river. Of the three fishes one of the fish was intelligent and one day he said to his friends that if the summer comes, the connecting tunnel will go dry and so they will have to live in an insecure pond and if somebody wants to catch them they will not be able to escape. The other fishes laughed at him but the intelligent fish swam through the canal to the river. Summer came and the canal dried up and the water level in the pond also went down. One day some fishermen came and they threw their nets and caught all the fish. The two fishes were also caught and they died. Thus prevention is better than cure in our daily life.
