But my life was a mess. I relaxed my standards. And stepped into a nightmare. Thursday morning I was the good doctor, focusing on my patients, determined not to let my own garbage get in the way of work. I kept my eye on the boy. He hadn't yet gotten to the part where he tore the heads off the dolls. I watched him pick up the toy cars again and advance them toward each other in inevitable collision. "Cah!" The ringing concussion of metal against metal blocked out the whine of the video camera before dying. He tossed the cars aside as if they burned his fingers. One of them flipped over and rocked on its roof like a trapped turtle. He poked at it, then looked up at me, seeking permission. I nodded and he snatched up the cars. Turning them over in his hands, he examined the shiny undercarriages, spun the wheels, simulated the sounds of revving engines. "Voom voom. Cah." A little over two, big and husky for his age, with the kind of fluid coordination that foretold athletic heroism. Blond hair, pug features, raisin-colored eyes that made me think of snowmen, an amber splash of freckles across nose and chubby cheeks.
