I haven't reread this whole thread, so please forgive me if I've already posted this anecdote.
I have a friend whose mother had some emotional/cognitive problems. The first time they watched
Carrie together, her mother was delighted when Carrie and the hot popular guy go to prom together. Just when Carrie and the guy are called up onstage and Carrie is at her peak of happiness, my friend sprang across the room and turned off the TV, leaving her mother to think the movie ended on that happy note, rather than in the mayhem that followed.
Someday, maybe my kids will do the same for me in the middle of the "sweet life" scene.
