Nothing is steady in life

You will meet several people in your life, you will have several friendships, several relationships in your life but as it is said, "You come alone, You go alone". No relation, no friendship remains eternally in your life, one day all will go away. Though you make thousands of promises with each other to stay together forever in their lives but only a few lucky ones get such a chance to be together forever.
So we should never get so attached to anyone that you become the Deepika Padukone of tamasha and you stop living life. And if you get attached always remain prepared for the seperation because your destiny you never know when qill it seperate you from him/her. Because such an attachment only hurts you. And you never even know the other person may even forget you and move on easily. And this realisation hurts you even more. This is a very very bitter but the ultimate truth of life.
