Smile

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