"I was just a boy, barely ten. My brother and ! wanted a dog, so our father bought us a greyhound. He'd spent years racing, had never been off the track. We took him to the park, and I remember the first time we let him off the leash. he spotted a cat, took off like an arrow. Killed that poor cat in an instant, tore it to pieces. Then he just stood there, confused. That dog had spent his whole life chasing after something, and it had no idea what to do when it actually caught it."
