Because they also, in the way old people often do, slipped gently into poverty. Also without anyone noticing. Poor is relative, of course. None of you were rich or had any dreams of being rich or even knew anyone rich. But the widest gulf in the world is the distance between getting by and not quite getting by. Crossing that gap can happen in a hundred ways, almost all by accident. Bad day at work and/or kid has a fever and/or miss the bus and consequently ten minutes late to the audition which equals you don't get to play the part of Background Oriental with Downtrodden Face. Which equals, stretch the dollar that week, boil chicken bones twice for a watery soup, make the bottom of the bag of rice last another dinner or three.

Cross that gap and everything changes. Being on this side of it means that time becomes your enemy. You don't grind the day-the day grinds you. With the passing of every month your embarrassment compounds, accumulates with the inevitability of a simple arithmetic truth. X is less than Y, and there's nothing to be done about that. The daily mail bringing with it fresh dread or relief, but if the latter, only the most temporary kind, restarting the clock on the countdown to the next bill or past-due notice or collection agency call.
