Once a mighty lion was sleeping in the forest. A little mouse accidentally ran over him and woke him up. The lion got angry and caught the mouse.
The scared mouse begged, "please let me go. I will help you someday! " The lion laughed and released the mouse.
A few days letter, the lion got trapped in a hunter's net. He roared for help. The mouse heard his cry and came quickly. It nibbled the ropes and set the lion free.
The lion thanked the tiny mouse. From that day, they became friends.
Moral :kindness is never wasted. Even the smallest friend can be the greatest helper.
