I don’t know whether anyone else does this, but once in a while I find myself asking myself how on earth I could ever get so lucky? I just got back from an early evening trundle to Greenwich Park. There is a vantage point there by the observatory which looks out over almost the entire metropolis: London stretches before you like a microcosm, with The City, Canary Wharf and The Dome laid out, left to right, in a panorama. I go there fairly often. This evening though, with the sky so clear and the lights of the city twinkling before me like the stars in a galaxy, I honestly don’t think I have ever seen anything quite so beautiful, evocative or inspiring. The moon was full and clear, shining down like a benign, caring night-light; the Thames snaking around the Isle of Dogs like a mother’s hand holding a newborn baby’s head. To think that I can just trundle out of my flat for a few minutes and have the greatest city on earth lying before me like that makes me realise how incredibly lucky I am.
