That's true. But even if you show it to others, its no use. As everyone is trapped in their own pain, they don't have time and effort to deal with other's pain as well. So its better to understand that life is about ups and down and keep your calm no matter situations are good or bad.

Thank you, nice replied :)
But, just understand is not enough at all. Everything is nothing without acting. Yes I know, everyone have their own pains and the only one knows is God. So, with understand about life we have to act as well as possible to be the better human :)
