I'm quite fascinated by the definition of British culture provided (British gentlemen, afternoon tea, the Oxford-Cambridge education system).
There really weren't any of the first in my 1970s childhood and I don't think I've really ever had any dealings with them - are these the people in bowler hats carrying briefcases from old newsreels? Afternoon tea I do remember in Enid Blyton books but has never been offered to me in real life. As for the Oxford -Cambridge education system while completely inaccessible to most of us I believe it is thriving?
