Incurable idiocy and ignorance. (Meme)
In short my mother was supposed to babysit my kids for 2 days because we had important matters to attend to. She knew about it well ahead.
She still decided to book a trip to a high-risk covid area for 2 weeks from which she was going to return the day before she was meant to be babysitting.
We informed her that we got another babysitter and explained her why. Oh boy she is fuming. She's a stereotypical self-victimizing boomer and man I am in the wrong once more for punishing her like this.
