What is the relation of happiness and sadness?

some people had experience it so i don't oppose anyway.. we really have to expect that in times of over happiness there will be a counter sadness for that ... that we have to overcome for those obstacles we are facing because life is not for a lifetime pleasure but there are also a combination of sadness.... so if you have encounter it right now you have to be careful with your move so you can avoid slightly a sadness moment of your life..... we can't predict what will happen to our life all we need is to enjoy though trials is there just ignore it... let your problem ....think of you not you were the one who thinks your problem.
