Jack's uncle lives alone in a village. This summer Jack went to him. He s his whole holiday there.
Every day they went out for a walk and he always saw his uncle at everyone. Jack didn't understand and asked, "Uncle George, do you know around here?"
"No," said his uncle. "Then why do you smile at them?" asked Jack. "Well, when I smile at someone, he knows me, he'll be happy. But when I smile at someone, even though he doesn't know me, he'll feel surprised and think, ‘Who is that man? Why does he smile at me?' He'll think these questions all the way, and he will be happy, too. So I give everyone happy feelings. I think it's for them to refuse the smiles."
"I see, Uncle George. Being kind to others is also being kind to o." Jack said happily.
