As the days piled up into weeks, and the weeks turned into months, and fall slid into winter, I realized one of the great truths about tragedy: You can dream of disappearing. You can wish for oblivion, for endless sleep or the escape of fiction, of walking into a river with your pockets full of stones, of letting the dark water close over your head. But if you've got kids, the web of the world holds you close and wraps you tight and keeps you from falling no matter how badly you think you want to fall.
