The ancient Chinese were a wise lot－wise in the ways of the world;and they had a proverb that you and I ought to cut out and paste inside our hats. It goes like this:‘A man without a smiling face must not open a shop. ’
      Your smile is a messenger of your good will. Your smile brightens the lives of all who see it. To someone who has seen a dozen people frown, scowl or turn their faces away, your smile is like the sun breaking through the clouds. Especially when that someone is under pressure from his bosses, his customers, his teachers or parents or children, a smile can help him realise that all is not hopeless－that there is joy in the world.
      Some years ago, a department store in New York City, in recognition of the pressures its sales clerks were under during the Christmas rush, presented the readers of its advertisements with the following homely philosophy:
      The Value of a Smile at Christmas
      It costs nothing, but creates much.
      It enriches those who receive, without impoverishing those who give. It happens in a flash and the memory of it sometimes lasts forever.
      None are so rich they can get along without it, and none　so poor but are richer for its benefits.
      It creates happiness in the home, fosters good will in a business, and is the countersign of friends.
      It is rest to the weary, daylight to the discouraged, sunshine to the sad, and Nature’s best antidote for trouble.
      Yet it cannot be bought, begged, borrowed, or stolen, for it is something that is no earthly good to anybody till it is given away.
      And if in the last minute rush of Christmas buying some of our salespeople should be too tired to give you a smile, may we ask you to leave one of yours?
      For nobody needs a smile so much as those who have none left to give!
