Case in point:
""We kept running over body parts," the fireman whispered. He was staring into my eyes with a pleading look, as if seeking forgiveness. "I mean, the ash was so thick, you'd see things in the street, but you couldn't tell what they were until you ran over them. I mean, what the fuck were we supposed to do?"
I nodded, patted him on the shoulder, and when I did, he let out a single sharp sob, almost like a hiccup. I looked past him at the 150 or so other firemen resting in a tunnel nearby."
