Once upon a time there lived a lion in a forest. One day after a heavy meal it was sleeping under a tree. After a while, there came a mouse and it started to play on the lion. Suddenly the lion got up with anger and looked for those who disturbed its nice sleep. Then it saw a small mouse standing and trembling with fear. The lion jumped on it and wanted to kill it. The mouse asked the lion to forgive it, "Let me go and maybe one day I will save you".The lion laughed, "What can you do for me, you, little mouse?" But the lion felt pity and let it go. The mouse ran away. 
On another day, the lion was caught in a net by a hunter. The mouse came there and cut the net. So the lion escaped. There after, the mouse and the lion became friends. They lived happily in the forest afterwards. 
 

Moral : A friend in need is a friend indeed.
