What couldn't they imagine you doing/ liking because THEY didn't do it/ like it?

I was just working while listening to a song I liked back in middle school, and suddenly remembered a moment when I was around 11-12 years old, studying and listening to music in my room, when my dBPD mom burst in, ripped my stereo plug out of the wall, and screamed that I couldn't possibly concentrate while listening to music (and thus, was listening to it to do badly in school on purpose, to make her look bad, lol).

Obviously, decades later, it turns out the only way I can concentrate on anything is with music in the background.

Anyway, all of this made me think: my mother was very easily distracted by music, so she assumed that...everyone was?

I have heard many times that pwBPD often assume that everyone's interests, motivations, etc are exactly the same as their own, but this was maybe when I truly got what that meant.

So I was curious: what things was your parent with BPD convinced that no one could do/ like because they didn't do/ like it? Big or small, silly or serious.
