Or maybe he means in a richer world the begging population is melting away. But no to that too. So maybe, perhaps, he means there aren't many 'human beings' left to look, see, and understand well enough for one to ask and one to give. Everyone busy, running, jumping, there's no time to study one another. But I guess that's bilge and hogwash, slop and sentiment.
I got a statistic for you right now. Grab your pencil, Doug. There are five billion trees in the world. I looked it up. Under every tree is a shadow, right? So, then, what makes night? I'll tell you: shadows crawling out from under five billion trees! Think of it! Shadows running around in the air, muddying the waters you might say. If only we could figure a way to keep those darn five billion shadows under those trees, we could stay up half the night, Doug, because there'd be no night!
