pain and joy

pain and joy, like we all know go hand in hand.
2 sides of a coin, that's how many of us refer to the ups and downs of life.

I don't know if i can refer to the strange feeling of seeing people go away slowly as pain.. To have known people, to have seen them as healthy, cheerful and warm people, and then to see them go away for no reason; for sickness to engulf healthy people, for some people to be able to muster the courage from within to face the sickness and emerge, for some others to not be able to do that.. All this happens, and we look on after everything that could have been done is done..
