My dad has not been too good this year and is no longer able to walk. He can't come to my house because loads of stairs. He is moving to sheltered housing and it is tiny, there's no room for a table. Going out is a possibility, although that will be a huge faff and I'm not sure he'll want to be bothered, especially as he is conscious of being messy when he eats. He's not really interested in anything any more, but I can't leave him alone either. What can I do?
