Grief, and how people handle it

I see the people waiting outside the ICU everyday. Relatives, mothers, daughters, wives, fathers and sons. My room being on the floor above the ICU, and adjacent to the relatives waiting room, one of the first things i see in the mornings sometimes is scenes of grief.I've almost developed a blind spot to that area, and i try my best not to look in that direction as i pass by. And i cant help but notice, how differently people handle grief.

Some people are composed. They try to be scientific about it and ask the doctor calculated questions.some people ask nothing and just listen to what the doctor is saying, not questioning his decisions. And then there are some people, who try their best to look grief stricken, appropriate to the situation, but their apparent sorrow doesn't reach their eyes. some resort to God, loudly and vocally. Some wallow in their own sorrow, silently without a word. Some blame others, looking for a outlet for their sorrow. Others accept the faith of their loved one.

But whatever the exterior emotions, only the person knows, what he truly is going through.

And I feel guilty sometimes in judging someone based on these superficial appearances.
