Just before 7.00 this morning, something weird happened to me. I was below stairs (so to speak) in my temporary kitchen, thinking about the multiculti builders arriving, contemplating last night's washing up and wondering how I was going to get anything done today with my five year-old off school, when the Today programme announced that it's the birthday of the Prince of Wales. And suddenly the national anthem was playing (this wasn't happening on Five Live, by the way - I checked). What did I think? That I should stand up immediately? No, I was doing that already. That I hate the bloody royals, string them up? Not exactly. Instead I thought what a surreally variegated nation I live in and how I quite like that, actually. Must be old age.
