Peter`s uncle lived in the country .once peter went to stay with him for a few weeks. Whenever they went for a walk and they passed somebody, his uncle waved. Peter was surprised, and said,” uncle Goerge, you know every body her. where did you meet them all?”

“I don’t know all this people,” said his uncle.

“ then why do you wave to them?” asked peter.

“ Well, peter,” answered his uncle,” when I wave to someone and he knows me, he is pleased he continuses his journey with a happier heart. But when I wave to some one and he doesn’t know me, he is surprised and says to himself,” who is that man? Why did he wave to me?” so he has some thing to think about during the rest of his journey, and that makes his journey seen shorter. So I make every body happy.
