The wind and the sun were disputing when who was the stronger.Suddenly they saw a traveler coming down the road.The sun said." Whoever can make the traveler take off his coat will be the stronger."
So the sun hid behind a cloud,and the wind began to blow as hard as it could.As the wind blew harder,the traveler wrapper his coat more closely around himself.
Then the sun came out.He shone on the traveler.The traveler soon felt quite hot,and took off his coat.
