Instead I wrote a list of the simplest things I could think of doing for the afternoon: office filing, doing some laundry, preparing something nice for dinner, finishing the book I'm reading and so on. At the top of the page was 'go for a long walk'. So I walked through London to a coffee shop on a busy high street, I bought a coffee, sat in the window and watched the Friday world go by, then I walked home again.
Sure the week ended with a whimper not a bang but at least I ended it with a sense of agency.
