"What sort of rules you have tends t'vary from vampire to vampire. Me, I just drain people I won't feel guilty about possibly killin'. I don't need t'be feeling miserable when I wake up the next night." Cooper was an odd sort in that respect. Most vampires killed without feeling anything. He'd been that way when he was young, confused, and bloodthirsty. Growing older had mellowed the vampire some. Now, he took prey as he saw fit, keeping away from those people that he already knew.
