The snake and the crab

Once there lived a snake and cab in a Jungle. The crap behaved politely with the snake in all simplicity and kindness. But the snake was always cunning, wicked and behave rudely. One day the crab courteously urged, Dear snake why don't you change your wicked ways and be polite. At the arrogant snake did not lesson. The next day when the crab found the snake was sleeping he grabbed his neck and squeezed him to that in anger. As the snake was dying is stretched out straight. The crab inside my friend if you had been this straight forward to begin with I would not have had to punish you for your crooked behaviour.

Moral: people who treat their friends rudely end up hurting themselves in instead.
