I think multiple generations need to pass before the population has any immunity to this sort of thing.

Unfortunately the scams will continue to develop in sophistication also.

My paternal grandma died last year. And my dad remarried in 2017.

Not really enough time for his new wife to establish much rapport.

Dad had always been a Mama’s boy and lived most all of his life clinging to his mom’s skirts anyway.

Yet when grandma died it was the new wife who casually sent me a picture taken with her phone of my grandma’s corpse in the hospital bed.

Horrifying, and very inappropriate. All of this is to say that I can relate to your situation and no, you aren’t overreacting.

Two that are related to falling

猿も木から落ちる [Even] monkeys fall out of trees [too]. Just because you’re good at something doesn’t mean you’ll always get it right.

七転び八起き Fall down 7 times, get up 8. Pretty self-explanatory
