I had a bit of a shock recently when I realized how politically correct I have become. Part of this I put down to my work across cultural divides, but part of it is also due to the changing social landscape of modern London. How different things were only 15 years ago. How we laughed at those politically correct diktats wafting across the Atlantic, proscribing our way of life and suffocating our jokes. But then it dawned on us that not everyone was laughing. And that you were the one whose throwaway lines were met with a steely challenge or a stony stare.
