glad to hear thing are going well, hope you friend is feeling more able to cope with him being in the home , photos of parents are good as they seem to remember their mum and dad also their brothers and sisters when young and of course pets, old songs from when he was young all seem to be remembered better then recent events, my mother in law could talk about her brother and sister but did not know who her sons were ,we were walking past a mirror 1 day when she said to me i know her in there ,i went to school with her ,i was never quite sure if she meant me or herself ,i always found it best to answer her as if i knew what she was talking about and never try to tell her otherwise ,they are in their own place in their heads which to them is real so i never saw the need to try and tell any different when other people did she just got confused upset or angry .all the best to your friend do keep in touch. ruth
