If there's one thing I know, it's this - everybody thinks somebody else is having a better life.

If you have any power at all from being popular, then you have a duty to help people out.

If, however, you have richer pursuits in mind and know that no woman should be judged by how she looks - that everything she brings to the party is more important than the size of her arse - then refuse to be sucked into the never ending whirligig of self-doubting, self-hating madness that is stop-start dieting and crazy new exercise regimes.

Statistically, if you have ever dieted you are extremely likely not only to regain any weight you lose, but to go on to gain even more. Dieting makes you fat.

My theory is that one needs to be loved completely, unconditionally, and unfettered by parental disapproval, if one is to get happily through life which, after all, presents its own hurdles.

I'm the co-chair of the PTA at my kids' school, Ashmount Primary, in north Islington, London.

Call me an over anxious, middle-class mum, but my eight-and-a-half-year old son looks very much, to me, like he's headed for a life of crime.
