The Wind and the Sun

The Wind and the Sun were arguing over which of them was stronger. They saw a traveller coming along the road, and the Sun said: "I see a way to settle this argument. Whichever of us can cause that traveller to take off his cloak will be the stronger one. You begin."

So, the Sun hid behind a cloud, and the Wind began to blow as hard as it could upon the traveller. But the harder he blew the more closely the traveller wrapped his cloak around him, till at last the Wind had to give up in despair. Then the Sun came out and shone in all his glory upon the traveller, who soon found it too hot to walk with his cloak on, and so he took it off.

And, the moral is.

Kindness and gentleness are more effective than aggression and anger.
