There are people living in London who come from all over the world and yet they by and large refuse to mix together
Do they?
I mean, I don't want to go all 'some of my best friends are black' or anything, but off the top of my head my household and I (who are all white and British-born) 'mix' with people who are from or who have backgrounds in Greece, Israel, Germany, Hong Kong, China, the Caribbean, Ghana, Nigeria, Jamaica, Iran, Spain, the US, Canada, Belgium, Australia, New Zealand.
I'm going out to a concert tonight.Off the top of my head our party includes four people born in Britain, two born in China, one in Sweden, two in Iran, one in South Africa, one in Greece, one in Ireland.Don't think we will refuse to mix!
