To Make Everybody Happy

Where did you meet them all?”

“I don’t know all these people.” answers his uncle. “Then why do you wave to them?” “Well, Peter ,” says his uncle “When I wave to someone who knows me, he is pleased. He goes on his journey with a happier heart. But when I wave to someone who doesn’t know me , he is surprised and says to himself, ‘ Who is that man?
