"I was alone in the middle of an endless, tightly packed city, where most of the inhabitants were safe in their impenetrable residence. Only unfortunates like me were stuck in empty, wet, fecal alleys, while the safe people had their pillow-top mattresses, thick down comforters, and feather pillows in their personal spaces each inch of which was warm and blissfully private. My stomach ached for food. I was cotton-mouthed thirsty. But I had worse things to fear, and every time I dozed off, I soon woke with a start, my eyes darting over the cobbles of the alley, knowing that the night was crawling all around me."
