Yarnspinner, that's exactly what the cat thinks. When I was a kid, we had a cat who would go up the stairs and meow at my sisters' door after they left for college. We had to go up and open the door and let him see that they were not in there, and after a few days, he'd quit. He did the same when I went to college, Mom said. But Ching was an exceptionally smart cat, and he hated to look foolish, so those two facts would combine to make him give up his search quickly.
