See, to me this is the biggest giveaway that she's achingly middle-class. She has that innate self-confidence to believe that she's genuinely brilliant at everything she turns her hand to - writing, singing, dancing, cooking, campaigning, modelling, styling her clothes, styling her home, you name it - in spite of being an absolute mediocrity at all of it. Working class people in my experience tend to be a bit better at having their kids be realistic about their abilities, only pushing them where they think they can truly excel. They know life is gonna bite them in the arse. This is only my experience of course but I've seen so many kids from well-off families think they're the absolute dog's knackers at things when they're just.... not.
