"Me walking around London is what I meant. "
Sorry ummm, I misunderstood.
I don't blame you for not walking round the areas I described. I wouldn't do it myself unless absolutely necessary (which thankully it isn't any more). But I still drive through these areas from time to time and you have to witness it or you would not believe it (which you seem not to). Thankfully there are still a good few places where the situation is somewhat more pleasant. Where I live is among them but if I had not been to the places I described I would not believe my description either!
