So you terrorized an elderly man with an infirm wife, Blackcat? Brave man.
Difficulties with hearing aren't the only invisible afflictions to affect the elderly. My mother was stricken with Alzheimers in her late fifties although for many years no-one outside her family would have realised that there was anything wrong with her.
My father, being loving and loyal, wanted my mother to have quality of life and get as much enjoyment as she could. He took her to all the places and events he knew she would enjoy and, along the way, he was helped by many kind and compassionate strangers. I'm sure this has made a big difference in mother's life.
If he'd taken her to the movies, she would have been able to see and hear it but not necessarily process the information quickly enough to follow the story. Dad would have helped her along with some commentary. I can only imagine how they would have felt if someone physically threatened them - and be thankful that no-one did.
