It went yesterday. The dissertation that is, the finished object, the monkey that has been perching on my back since May. But to my surprise, instead of feeling the expected elation, I felt rather subdued, as if something was not quite right, a little bit low even. So this weekend I expect a little bit of isostasy, a rebalancing. No big celebrations. Just enjoying the morning mist and the sunny afternoons. Some fresh air, seaside, allotment. That'll do.
