I've got very sore feet today. I went to visit Gavin in London at the weekend. On Saturday evening he said that he was tired and wanted a quiet evening and an early night. That's great, I thought. I didn't realize that "a quiet evening and an early night" involves visiting 3 or 4 pubs, a jazz bar, and a restaurant, and walking about 300 miles around Southwark and Soho, before crawling into bed at 1am. I just can't keep up with the youngsters any more.....
