A Heart So Closed

We've all met them, the self-involved ones, those that rationalise, the very shallow, the weak among us, the materialistic, the ones that smile when they lie. Sadly, we've all met far too many of them in life. I wonder about these people. Just what do they say to themselves at the end of the day? How did all this begin for them? A heart so closed can't possibly have been born that way…or could it?
