Size matters... or does it? Jay has always envied her cousin Delphine. While Jay was brought up in a large, noisy and chaotic family, Delphine was indulged, perfectly dressed with an immaculate wardrobe and dancing lessons. Now Jay lives happily with her architect husband and their three teenage children, running a successful company, while Delphine has long since disappeared to Australia with her second husband. But Jay still wonders if she should be more like her cousin with her size ten figure. So Jay decides to diet. But what shoult it be? High carb, no protein? High fiber? Wheat free? She tries them all. And once Delphine reappears, with the same old air of effortless superiority, the old envy returns - but who exactly is envious of whom?
