My grandma turned 93 today. It's been a tough year for her. Things haven't gotten a lot better since her stroke about a year ago. Fortunately, they haven't gotten worse either, and she's been pretty stable. But it's still awfully sad and frustrating, and it's been a real loss. She knows who I am, and her long-term memory isn't bad -- she remembers things from her past, she remembers fundamental things about the world and her life and, in the moment, she makes a lot of sense and can carry on a conversation. But her short-term memory isn't there, and new information just doesn't stick for more than a few seconds. So every day, it's the same conversation, more or less, at least on her end, changed only based on however it is I respond."
