It was a hot summer day. Sun was shining bright up in the sky. A lion was sitting under the shade of a big tree and in some time got asleep. Nearby that tree, there was a hole, in which there lived a mouse. When the lion was sleeping, the mouse came out of its hole and saw him asleep.
Unaware of the lion’s strength, it got tickled by an idea. It thought of waking up the lion by running over his body just for fun.
Unfortunately, the lion seized it in his strong paw. He was going to kill it when it begged, “Spare me, sir; some day I may repay your mercy.”
The lion was amused hearing it’s words and let it go with a smile thinking that how can such a small mouse be of any help to me.
But a day came, when the lion got into trouble. He got caught in a hunter’s net under that very tree. As a result, he started roaring loudly.
On hearing his roar, the mouse came out of its hole. This was the time to pay back the lion’s mercy. So, immediately it nibbled the cords of the net and set the lion free.
Remember, mercy never goes unrewarded.
