The Smile That went Around the World, by Patrice Karst is a book that reminds us of the power of a smile. Mother Teresa said, "We shall never know all the good that a simple smile can do." This book starts with the simple act of sharing some cookies with some people who were hungry. The boy sharing the cookies feels so good he smiles, and that smile sets off a chain reaction that goes around the world. Smiles are powerful!
