For example, he is so disappointed that my brother never visits. My dad is in a nursing home and my brother lives in another country. I told him for a few weeks that it was impossible for my brother to visit and it finally registered. But once in a while he goes back to asking why my brother never visits. Should I go along with this? It makes him really sad that his son never comes to see him and when I tell him he is abroad he goes back to remembering even for a brief while. In a second case scenario he mentions a fight he had with his (deceased) friend. This imaginary fight upset my dad for months and even kept him up all night. Should I still go along with this? My dad has been able to admit he dreams a lot and can't distinguish what is real and what isn't. Is it ok to say that perhaps he dreamt it?
