Admitting needing help when her scooter died and admitting she couldn't walk to the examining room from the waiting room has me baffled. She's a simpleton, yet the way her brain works confuses me completely.
Those are just minor inconveniences. The big deal is she has to fight the blokes off every laboured step of the way. It's hard work having to haul those legs over every guy that's thrown himself prostrate at her trotters.
Being serious, her reasoning comes over so distorted because it's a mirror of her mind. Others have pointed out she's always been big, she has the learned manipulative cunning that serves her sufficiently to get what she wants, and she's developed a host of unhealthy coping mechanisms, like knee-jerk lying to avert censure (dumping cats on Rafe, the "broken" scale and a million other fiascos) and a huge wall of denial - whatever big lies she tells are the comfort lies she also tells herself because gnarly old reality is too much.
I don't think she knows how to be comfortable with the truth. Either it's slip-ups which she then has to own when she's caught bang to rights, or these moments where she is really seeming to tell us something are actually moments where she's testing out the actual truth on herself. Then it's too much and she backs away from it, usually by a cover-up or equating it with drivelling nonsense and it comes over as deceitful or flippant. But you can find the pattern over and over - "I get stuck in the shower" is a big deal and the softening or reducing statement that follows - "I have such a pretty face" isn't for us. It's for her.
And, despite devotimg her entire life to contemplating her own Marianas Trench of a navel, she has absolutely zero idea why she behaves the way she does, so has zero idea how it's seen from outside. She doesn't realise it comes over as mendacious and solipsistic and we can't understand her the way she wants to be understood because she can't be honest with herself . And there you have the fascination for a lot of us.

r she's a stunted immature mess and she needs a fucking therapist.
