Smile is a kind of language. When you meet somebody,smiling always means that you are a kind person. Nobody will hate to talk with a person with a smile on his face. A saying goes, "Life is a mirror. If you smile to it.it will smile to you.”I think keeping smiling in life shows you are an optimistic person. We can make our life better if we often smile.
