Is smile just a facial expression? Of course not! It is not only used to express pleasure, affection, and friendliness, but also the commonest way to show our good will perfectly without saying anything. A Chinese saying runs: "Never hit a person who is smiling at you." It is a time-proven fact that smile is a language all its own-a universal language-understood by the people of every nation in the world. We may not speak the same tongue as our foreign neighbors, but we smile in the same tongue. We need no interpreter for thus expressing love, happiness, or good will.
One day while shopping in a small town in southern California, it was my misfortune to come across a clerk whose personality conflicted with mine. He seemed quite unfriendly and not at all concerned about my intended purchase. I bought nothing, and marched angrily out of the store. On the outside stood a young man in his early twenties. His expressive brown eyes met and held mine, and in the next instant a beautiful, brilliant smile covered his face. The magic power of that smile made all bitterness within me melt, and I found the muscles in my own face happily responding. "Beautiful day, isn't it?" I remarked, in passing. Then, obeying an impulse(冲动), I turned hack. "I really owe you a debt of gratitude," I said softly. His smile deepened, but he made no attempt to answer. A Mexican woman and two men were standing nearby. The woman stepped forward and eyed me inquiringly. "Carlos, he no speak English," she volunteered. "You want I should tell him something?" At that moment I felt changed. Carlos' smile had made a big person of me. My friendliness and good will toward all mankind stood ten feet tall. "Yes," my reply was enthusiastic and sincere, "tell him I said, 'Thank you!' " "Thank you?" The woman seemed slightly confused.
I gave her arm a friendly pat as I turned to leave. "Just tell him that 
" I insisted. "He'll understand, I am sure!"
Oh, what a smile can do! Although I have never seen that young man again, I shall never forget the lesson he taught me that morning. From that day on, I became smile-conscious, and I practice the art diligently, anywhere and everywhere, with everybody.
