The gift needs to be able to come off as a genuine gift so there’s some plausible deniability…
Edit: Just so it’s clear, this is purely hypothetical. I just thought of the idea and thought it would be funny to see what a random person on Lemmy might think. This isn’t a serious request and none of the suggestions will ever actually be used.
My personality disordered MIL is an artist at giving insulting gifts. An absolute master. She likes to pretend she is very poor, although isn’t, and she volunteered at a Catholic charity shop for used goods, so she would take home armloads of used crap donated from the homes of deceased elderly people and would give them as gifts, none of which was any use to anyone and was quietly donated elsewhere afterwards. But she also likes to give you weird things that are basically trash, not because she can’t afford gifts, but just to get negative attention and make people upset.
Top tier personality disorder behaviour really.
My goodness, she sounds like a monster. Continue doing your best to protect the granddaughter please.
