BE TRUTHFUL

Once lived a mother and a son. The son used to lie for fun, but the mom did not know anything. The next day a milkman came to say "they haven't paid money for the milk". They knocked on the door. The boy opened the door. The milkman said, "hi little boy is your mother there?" the boy replied, "no my mother went outside" the mother saw her son lying and said to the milkman "sorry here is the money" and gave the money. 

Now the mother tells a story to her son "once in a village, a boy use to lie, one day the boy came and said lion! And everyone came after everyone realized the boy lied everyone got angry. The second day he again said lion! Everyone came and everyone got angry again. On the third day he did the same thing, everyone came and got really angry. On the fourth day a real lion came he really shouted lion! But no one helped" so don't lie.

Moral of the story: if you tell one lie you will have to say mountains of lies to cover it.
