Tears are the good things that can help people get rid of bitterness. But when we grow up, we will gradually learn that there are some great sorrows in our lives that can not be easily handled with a burst of crying and there are some occasions when we must control our tears even though we really want to cry. So the strongest people are those who laugh much more loudly when they are about to break down and are those who keep smiling and moving forward on with the unforgettable bitterness deeply hidden in their hearts.
