You have described the treatment of my 90 yr old father who's in hospital now. Bored out of his mind, staring at a wall all day and given disgusting food. My Mum and I go in at lunch time every day with his favourite food, and chat to the other inmates. The carers didn't like it at first and told us many lies about food hygiene and a broken microwave but they're used to us now.
Go to youtube and search Katherine Nutbeam singing in her yellow dress - Somewhere along the Road, for her father; it's wonderful.
