So due to various reasons I don’t really care if my entire family gets tied to train tracks and run over tomorrow, but I still think it’s blithely comedic
Now that my dad is entering the Biden stage of his life, my siblings have started to fight over who gets what (By which I mean the shitty furniture in the house; also I got cut off a long time ago lmao 
)
Apparently my brother is now demanding “unpaid rent” (at $3000 a month, over 16 years) from my dad because he lived with him and had to deal with the “mental anguish” and “caretaking responsibilities”.
The kicker is that my dad was always whining year after year about him living in his house and threatening to kick him out time after time (he never did). My brother was always whining about living with the old man too (he has his own house sitting empty that he can move to at any moment). They basically live entirely separately within the house lol.
It also came out that he was also siphoning money out of dad’s account (in addition to half of the pension that he somehow convinced dad to give him). Now my sister is mad and saying she should get the other half.
I found out about all of this after he sent me a five figure “invoice” for “caretaking services”
Sounds like your brother needs a horse kick to the face. Not saying your sister might not also suck, but your brother really sounds like the villain here. I would conspire with your sister to try to deal some justice to him. Or you could always just detach from all of them.
I have. Since they don’t know my phone number they just send angry letters in the mail about this or that. Sometimes I even read and chuckle at them before chucking them in the trash.
The “invoice” got my attention, but I’m not being dragged back into that. Frankly they deserve each other.
Only reason I posted about this latest stunt is because I think it really lays bare how transactional and shallow it all is.
