A thousand times this. Not only do abused people not know any better, they're actively prevented from knowing any better. It's how abuse works. It's especially terrible when parents do it, because children are naturally, genetically predisposed to try to seek approval from their parents. If they can't get it, or if it's contingent on something as arbitrary and pointless as playing a piano, it will destroy them for life. I'm not a parent, and after my childhood I didn't think I'd ever want to be, but reading that article gave me new hope for myself: if anyone tried to do to my hypothetical children what the author is doing to hers, I would kill them. Instantly and brutally. That's got to be some kind of a qualification.
