"Daddy could probably be persuaded to buy me that tiny sparkling phone, but I'd need the tiny silver shoes and the tiny sequinned dress to go with it. And would I fit into the tiny sequinned dress ?"

And so Peaches trotted on through the Great Mall of All Time, pondering this deep and difficult question.

"If I eat a fragment of chicken and two peas tonight... and if I eat a sliver of fish and half a cherry tomato tomorrow. And a wafer of ham and a pineapple cube on Thursday. And a shred of Sushi on Friday. Then I might just fit into that tiny sequinned dress by Saturday.....

But maybe not....."

By Saturday Peaches was pale and wan. She was also cold and jittery from all the Diet Coke she'd been drinking. But she was definitely thinner. There was no doubt about it.

And in this very thin and spikey condition, Peaches set off through the Great Mall of all Time, looking at herself in all the windows and mirrors she passed. And all the time saying to herself, "Who IS that fantastically thin person ? It's ME! It's ME! It's REALLY ME!"
