So I'd written a bunch of stuff to post here, but then it all reminded me of this quote from American Beauty, so I may as well just leave that with you. (As well as a bunch of grey, sad photos I took while walking from St Paul's Cathedral to the Tower of London.)
"It was one of those days when it's a minute away from snowing and there's this electricity in the air, you can almost hear it. And this bag was, like, dancing with me. Like a little kid begging me to play with it. For fifteen minutes. And that's the day I realized there was this entire life behind things, and... this incredibly benevolent force, that wanted me to know there was no reason to be afraid, ever. Video's a poor excuse, I know. But it helps me remember... and I need to remember... Sometimes there's so much beauty in the world I feel like I can't take it, like my heart's going to cave in."
