When he came back a few days ago, he was alert enough to be happy to be home, but since then he has had to have so much medication that he seems to have forgotten he was here and kept asking where the nurses were. They have him more heavily sedated at the hospice house, so he might not even know he's been moved again, but at least they'll be able to keep his pain under control. I hope his dreams are more pleasant there than they were here.
Meanwhile my mom's Alzheimer's is so advanced that she didn't even recognize my dad when he came back. She thought he was her dad, who died some forty years ago. My dad is now so hard of hearing that he didn't realize that she thought that she was talking to her dad and not to him, so in a way they both enjoyed their reunion, I suppose. Given the circumstances, we chose not to enlighten them to the misunderstanding. Old age is difficult enough without reality intruding on it. I hope to be eaten by mountain lions before I reach that state.
