There was this old man who saw a scorpion floundering around in the water.  He decided to save it by stretching out his finger, but the scorpion stung him.  The man still tried to get the scorpion out of the water, but the scorpion stung him again.  A man nearby told him to stop saving the scorpion that kept stinging him.  But the man said: "It is the nature of the scorpion to sting. It is my nature to do good.  Why should I give up my nature to do good just because it is the nature of the scorpion to sting?"

MORAL OF THE STORY:

Treat everyone with politeness, even those who are rude to you - not because they are nice, but because you are.
