I feel your pain, I have a friend who is suffering right now, I call him and he remembers me, his wife said when I call, he gets happy and like his old self, but he is not going to get better . Which is really sad because he has such great stories and history, from driving a tow truck during the Watts riots 5o being the crew chief for Brumos and the history in between is just as fascinating.
I don't know what is worse, losing a friend like that with such amazing history and knowledge to share or watch them deteriorate
