Ah yes, but once looked and never looking again, the sight tends to fade, does it not? Even vivid memories dull after a while, or mutate into a fable of a story of a truth. London will have not forgotten me. A city never forgets. A hundred years, or two hundred, or even so far back as time unmemorable, the city will remember. Man's memory will forever shift and sway like a thin curtain and that can't be changed, but a city's memory lasts, sir.
