Well, that's my point. I see people hung on my apparent dismissal of "bad blood", but that wasn't the core of what I meant. I just can't imagine how people can end up in a situation where they'd be actively getting rid of their elders over Christmas[0] by faking or causing illness to them. There's a difference between refusing to visit or care about someone you don't like, and getting them admitted into a hospital to get rid of them for a few days.
