"I love you," she said, dispassionately. "You're my puppy. But when you're really dead you get to see things clearer. It's like there isn't anyone there. You know? You're like this big, solid, man-shaped hole in this world." She frowned. "Even when we were together, I loved being with you. You adored me, and you would do anything for me. But sometimes I'd go into a room and I wouldn't think there was somebody in there. And I'd turn the light on, or I'd turn the light off, and I'd realize that you were in there, sitting on your own, not reading, not watching TV, not doing anything."

He was a jerk sometimes, and he could be a joke, and he loved to have mirrors around when we made love so he could watch himself fucking me, but he was alive, puppy. He wanted things. He filled the space." She stopped, looked at him, tipped her head a little to one side. "I'm sorry. Did I hurt your feelings?"
