It's so sad to see her refusing to move on from this obsession with being skinny. She wants it just to post it too. All that free time, money and connections just to waste it on spending your whole day taking pictures from mad angles to try and get your bones on show. I imagine a lot of it is a competition in her head with Olivia. Says a lot that she thinks Olivia is where she is because she's thinner and not because she obviously tries a lot harder (still a nasty social climber) than flossie. Will be heartbreaking for her when she's older and realises she spent her youth fruitlessly pursuing nothing.
