REALITY?: Another of those “marriage” moments

The man has had a hard day. He’s sitting in his leather chair, feet propped up on the matching hassock, nearly asleep. His loving wife has an idea. She goes and gets his slippers, kneels beside the hassock and unties his left shoe. He wakes and asks her what she’s doing, smiles at her thoughtfulness. She gently pulls his slipper on. The man laughs. She adjusts it a bit on his foot. He is still laughing. Without a word he uncrosses his feet and she can clearly see she’s put his left slipper on his right foot.
