I think Sophie really wishes there was no such thing as food, she probably would be happier if all her family could just eat a shake or pill or something with the minimum amount of nutrition in it rather than actual food. She clearly gets no enjoyment from food or cooking, we've seen the slop she and jamie"cook", but do we ever see them going out to a lovely restaurant and showing the delicious food? I would expect that to be a normal part of life for a well off couple with on hand babysitters. I can't recall them ever going out for a meal as a couple or with children. I appreciate it can be difficult with children, but I'm a firm believer in taking children out to eat from a young age so that they quickly learn acceptable behaviour in public, but she doesn't even seem bothered about manners at home.
