What is sport to one is death to another

Once there was a pond in a certain village.The pond was full of frogs.The frogs lived there peacefully.Some of them put their heads out and croaked loudly.One day some noughty boys were returning from school by the side of the pond.They heard the croaking of the frogs.

Suddenly they hit upon a plan.They collected some stones and began to throw them into pond.At this, the frogs went into the water.Some of the frogs were brutally injured and some were killed.After a while,the frogs put their heads out of water.

Then the boys started to throw the stones to them.And then the frogs again went into water.The boys continued throwing the stones to the frogs.They took it as a fun/game.They were enjoying it.

At last an old frog raised its head and said "Oh noughty boys!What are you doing?We are dying.""We are playing and enjoying it."the boys replied.Then the frogs replied,"What is sport to you is death to us.Please stop this cruel fun."Then the boys realised their fault.They apologised to the frogs and left the place.
