I visited London in October, 2012. I’d never been before. One thing I noticed was an almost complete absence of white people. Other than tourists, the only white people I saw were the men driving the “black” taxis -a job that requires memorization of every street and alleyway in all of London.
My son and DIL visited London at the end of 2017. When I asked him how they liked it his reply was “Europe is lost”.
