Unfeeling

I never understood why humans were so self centered, cold blooded, unfeeling and shrewd.

How can one read a book that is thought-provoking, and not wonder why the Author wrote such a thing so affecting and out of the box? How can one walk pass a blind man playing the guitar, singing and whose shirt is soaked with sweat and not give a second glance or thought about it? How can one go through a painting and not wonder what made the Artist draw that particular painting? How can one for wealth, break another's rice bowl? How can one not feel when you see hunch-backed elderlys, digging into filthy bins for trash cans just for a $10 or lesser for 200 cans in return? How can one not feel about everything, other than himself? How can you not give a thought to anything whether minor or not? How can any of you NOT feel or think?

Is everything insignificant to humans? Is self-centering more vital? How can it be...?

Is my naivety or emotive the answer to all these "unimportance"?
