the downward spiral

Went walking yesterday, following the path, more or less, of the River Westbourne, one of London's several underground rivers. Unfortunately, most of the people who were supposed to join me pulled out, and, with just the one companion, what was meant to be a pleasant and historically/geographically interesting jaunt in the good weather turned into a glorified pub-crawl. Not necessarily a bad thing, but not what we originally had in mind. Went to Brick Lane for a curry, though.
Hungover, again. Anyone spot a theme?
