Help help help help help! Everything's normal here. But the "When are we going home?" conversation has gone on longer than ever today, a bit like a long rally at Wimbledon. I know the same conversation is taking place in hundreds, even thousands of homes where there's someone with Alzheimer's.If only there was some way of distracting them from that delusion that they can go home. All I can do is suggest a cup of tea first.
