The library was one more essential in the parade of rooms in a big 18th-century house - and part of the required kit ever afterwards. The important thing was to have the books, not actually read them.

By the late Nineties, we had become a more visual nation. Big-money taste moved to global standards - new architecture, design and show-off contemporary art. The Sloane domestic aesthetic - symmetry, class symbolism and brown furniture - became as unfashionable as it had been hot in the early Eighties.

It's just as well that I write in the same facile way wherever I am - no blocks or anguish, no contemplation, no elaborate revision, no need for love-tokens or nice views.

Girls like Diana Spencer, armed with nothing more than a guinea-pig-rearing certificate, proud to say in that old Sloane way that she was 'as thick as two short planks,' became the exception as girls from Benenden and Downe House started to fast-track towards the City and law, consultancy, media and the arts.

Prince William looks good in uniform and Man-at-Hackett black and white tie (he has grown up wearing it constantly); less certain in his suits, which sometimes look borderline archaic; and variable in casual. But completely comfortable in the Sloane uniform of non-designer jeans and chocolate-brown suede loafers. He'll look fine in Boden.

The old process of social assimilation used to be mainly about English new money - generated in London, the mucky, brassy North or the colonies - buying those houses and restoring them, and doing the three-generation thing, mouldering into the landscape, and the 'community,' identifying with the place in a familiar way.

Socially smart people have always mocked the threateningly mobile, and anti-branding is a central strand of high-end status conflict now.
