I had half an hour or so to explore the streets of South Kensington on Wednesday. I was amused to find that people cover their Rolls Royces and Bentleys in this neck of the woods. This seems remarkably modest and quite the opposite of one-upmanship, or maybe it's just to keep the leaves and bird poo at bay. I really like the suggestion of form and shape sheathed in grey fabric, hugging the expensive, polished machine beneath.

One of my highlights of this trip to London happened in the tunnel from the museums back to South Kensington tube station. A group of twenty or so infant school children were walking with their teachers slightly ahead of us, when some of them started to sing Twinkle Twinkle Little Star. This built and built as more of them joined in and the sound reverberated around the tunnel. An elderly busker realised what was happening and joined in on his guitar, grinning excitedly at the opportunity of a spontaneous jam. The whole thing only lasted 15 seconds or so but was electrifying.
