The Old Lady's nap

The Old Lady has taken up napping in the dog's bed. This leaves Sally flummoxed, since she recognizes that the cat has higher pack status than she does, and if the cat is in the Sally's bed, the dog cannot get into the bed until the cat invites her. The Old Lady will not be inviting her, as she cannot imagine anyone waiting for an invitation. This is how I know that we will not be able to effectively communicate with creatures from other parts of the galaxy, when they arrive on earth. Maybe they've already been here and left, looking for a more understandable species.
At any rate, the Old lady is in the dog bed only because she cannot jump up on the couch, her preferred nap space. When I do find her napping on the couch, I know that she tried and failed at least twice, before her old, wasting hind quarters could launch her from the floor to the couch. She will not use the kitty steps I have placed for her.
Everything has changed, and nothing has changed. Youth is gone, and with it, the competent comfortable body. Expectations have not changed. I expect to nap on the couch. I will probably use the kitty steps.
