I lived in Stratford for several years, when it was darker, quieter, a wilderness of canals and disused yards. We would walk along the foetid water’s edge, the world of water rats and urban foxes, on shabbat afternoon. We moved away. One day it was gone, replaced with an Olympic Stadium and a huge mall. The wilderness became the centre of the world for a few weeks. I return, and I admire the clouds.
