Smiles

A smile costs nothing but creates much.It enriches those who 31____, without making those who give poor.It happens in a 32____ and the memory of it sometimes lasts 33____.None are so rich that they can get along without it,and none so 34____  but are richer for its benefits.It creates 35____ in the home,and fosters good will in a business.It is rest to the weary(疲劳的)，daylight to the 36____ and sunshine to the sad.

Yet it can't be bought,begged,borrowed,or stolen,for it is something that is no earthly good to anybody till it is given 37____. And if in the last-minute rush of Christmas 38____, some of our salespeople should be too 39____ to give you a smile,may we 40____ you to leave one of yours? For nobody needs a smile so much as those who have none left to give!
