Everything happens for some reason and this ignites our emotional state .Some of them are driver of our actions. We often meet people unintentionally in our lives without knowing that they would become our well wishers someday. If that wavelength matches then beginning of sweet responsibility starts just like early sunrise brought with it a new rays of hope in their lives.
meanwhile if fragment of our past confronts you it takes us by complete surprise and find ourselves in the middle of a troublesome situation where you have to answer a question you solve (happen=reason)by this formula at least problem will be minimize. Don't let your heart be volcano.
Do believe that someone somewhere is happy knowing that you are happy. So always smile and work hard to achieve your dreams and goals.
And of course do believe that things happen....happen...happen..till life.
