When I watched this guy's wife said that he treated her like his guide dog, every time he needed her he whistled. She said she felt that she was being used by him as a guide dog whenever he needed her. I felt sad for her at that moment. And I didn't believe that later when they prayed together and decided to be together no matter what was what really changed her hurt feelings or just recovered from his heartless use of her. I think that she had pointed out the way he treated her was wrong and unacceptable, and she might have said if you keep doing this kind of thing treating me like a dog, I'll leave you. I think that's the real alarming message to make him realize how heartless he was and finally recognized she was not his guide dog but his lifelong partner and companion. I also noticed when she mentioned it, she still showed a hurt feeling.
The other thing made me wonder is if both him and his sister got the same peculiar blind disease at the same young age. It means that there's some weird genes from their parents. The documentary didn't tell us whether their parents and among their ancestors got this disease. I also noticed that their adult son looked quite healthy and normal, but I just couldn't worry about whether that sort of weird genes still existed and hidden, it might skip his son's generation and transfer to his offspring. Or that cursed gene would skip couple of generations and reappear in the future. This possibility is there, and I think all of them might have the same fear, but just buried it deep in their minds. What a weird disease.....Is there any recorded statistics telling us how many people suffered the same early blindness? Is it a racial biased disease only happened to certain races? Lot of questions...
