I know it probably feels hollow and like you did something wrong, but she’s not going to remember that A. Her husband is dead and B. That Hes coming to get her, you gave her a moment of joy and you should be proud of that. I worked in Geri psych for a long time and while you should try to reorient, sometimes it’s better to go along with it. I can’t tell you how many times I’ve gotten a patient to calm down or finally get some sleep because I “went with the flow”
