That certainly sounds strange…I’ve never seen someone’s eating habits change drastically like that. I have no experience with people who have had strokes, so I can’t speak to that. But my first thought on reading your account was that perhaps he can’t chew/swallow his food as well as he used to, and that’s why he cuts his food up so meticulously. And then, maybe, he is embarrassed of this fact, and that’s why he eats so quickly. Just a thought.
