The king and the foolish monkey

Once there was an able king ruled in a kingdom. He loves animals so that he had a pet monkey. This monkey was a fool, but was treated royally and moved freely in the king's palace. King was given all the freedom to the monkeys. He was also allowed to enter the king's personal rooms that were forbidden even for the servants. It was happy with the treat given by the King.

One afternoon, the king was asleep, while the monkey kept watching to him. All of a sudden, a fly came in the room and sat on the king's chest.  The monkey influenced him away, but the fly would only go away for some time and return on the king's chest again. 

The monkey got very angry and excited with this fly's activity. The foolish monkey started chasing the fly with a sharp weapon. 

As the fly sat on the king's chest again, the monkey hit the fly with all his strength. The fly flew away unharmed, but the king was severely wounded in the chest and at last he died. 

Moral:

Beware of a foolish friend. He can cause you more harm than your enemy.
