Do you mean in general, or home health related?
One of my favs was a lady in a nursing home. She called herself "Kathleen the Irish Queen." She had some form of dementia, so every time you'd see her, she'd have forgotten all your interactions in the past. We had worked together several times. But she'd introduce herself by that moniker. She'd try to make people feel at home, smiling and welcoming whoever passed by. You could not help but feel loved, I know that wasn't HER job but mine, but I still enjoyed her tremendously!
