I vote that on 9/11, an unbroken chain of utterly cheerful and friendly Brits passed me from one to the next, getting me home from Aldgate to Brent Cross, when I had absolutely no idea how to get there because I'd always been on the Tube, which was down. They shoved me on overcrowded buses, walked me along, cadged me lifts, no-one ever accepting any money. That's the British spirit at its best to me, which underpins British culture.
Architecture - look at Salisbury Cathedral, and St Pauls, look at the houses still standing 300 years later.
Artists - look at Stubbs, Reynolds, Turner, Banksey. . .
Writing - where would we be without Jane Austen, Beatrix Potter, A.A Milne, C.S. Lewis, George Eliot, Chaucer, Shakespeare and Dickens?
And I'd hate to live in a world without British Beer and Pub Grub!
