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.

Sloanes aren't cafe society or NYLON hedge-funders with million-pound bonuses, or London Eurotrash wearing upgraded style anglais. Ann Barr's and my original picture of them in 'The Official Sloane Ranger Handbook,' published in 1982, was of an upper-middle-class world, conservative and fairly homogeneous, united by old attitudes and institutions.

Rock and roll is the hamburger that ate the world.

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.

My friends adore 'TOWIE' - the TV documentary series, 'The Only Way is Essex.' They like it, I'm afraid, for the most unworthy of reasons: class mockery. They tune in to wonder in a 'can you believe those people?' way at the natives of Brentwood and Buckhurst Hill.

I can't actually read interviews with thesps now because they're almost always fantastically predictable, the men especially. Actors are forever stressing their ordinariness, their beer and football-loving commitments.
