There was an old owl that lived in an oak. Every day he saw incidents happening aroundhim. Yesterday he saw a boy helping an old man to carry a heavy basket. Today he saw a girl
shouting at her mother. The more he saw the less he spoke.
As he spoke less, he heard more. He heard people talking and telling stories. He heard a
woman saying that an elephant jumped over a fence. He also heard a man saying that he had never
made a mistake.

some became worse. But the old owl had become wiser each and every day.
