This well-known Ancient Greek tale "The North Wind and the Sun” is my favourite Aesop’s fable.

There are many interpretations as to the meaning of the fable, I think Aesop’s fable basically says that if you want a man to take off his coat, you don’t blow it off. You make him feel warm, and he’ll take it off on his own. A metaphor is often used in framing a dispute or situation and you can use this fable as a metaphor for negotiation technique.
