It very well could have not been a joke, it did look like he was upset when he grabbed the back of his neck. But, I am very confident that if he was actually mad about it.....it was the disease causing the anger....not because he has any issues with him.Yeah, this. I don't think it was a joke. I think it was a man(Knight) not understanding. Its how it is with my wifes dad. He had a stroke. Nowhere near the person he was. His reaction to things now, are not what they were before.
