humanity...hmm maybe in the same words we would describe love , friendship , sacrifice,patriotism ...
I guess somethings can't be described, they just exist boundless of words. its not only caring,sharing and sympathizing with others....its probably feeling the pain,thrill , happiness ,anger or any other emotion like it was the situation happening with your self. And to help the person ahead we might go out of the way.I think words cant describe it.
