Now where was I?

Sirius has a habit of getting my attention to get me to walk to the back of the house with him to pet him while he eats some of his food. Just now we were about half way to his dish when he had to stop and scratch an itch. It must have been an especially annoying itch because it took him longer than usual to get it sorted out. When he finished fixing his fur he looked around, then glanced up at me as if he'd forgotten I was there and, oddly paused as if to say, "Huh, what was I doing?" It didn't take him long to remember, but the hesitation was funny.
