Scorpion?

There was a 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. Another 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 love. Why should I give up my nature to love just because it is the nature of the scorpion to sting?"

Don't give up loving people... Don't give up being good... Even if the people around you hurt and sting, love them.
