Me: Can I go to Blackhorse Road, please?
Him: Near Tottenham? How did you end up here?
Me: No Victoria line. Buses would take ages and I have an 11-hour day tomorrow.
Him: An 11-hour day? So, when are you going to become a billionaire?
Me: *laughs hollowly* Oh, I don't think that's very likely. I'm a librarian.
Him: A librarian?!! Oh, Jesus Christ.
After this edifying encounter he then explained to me how the only way we could save the planet was to work a 2-day week (hang on, not all of us are taxi drivers...admittedly I was IN the taxi at the time, but I don't think I cause that much more environmental damage by recycling books for an extra three days a week...) and told me his views on vegetarianism ("Not natural for chickens to lay eggs twice a day...chickens lay eggs ONCE a day, more than that's not natural.") When I said I was a vegetarian and bought free range organic eggs he said he "wished" he was a vegetarian. Yeah, well done there mate.
Journey cost me £25.
Worth it to see friends for once though.
Also, just seen The Golden Compass... Going to remain quiet on all the obvious ways in which it differed from (and was worse than) the book, but more importantly: Lord Asriel's research proposal was CRAP!! If I was Dean of an Oxford college there's no way I would have thrown away research funding on him, even if he did wear a convincingly professorlike lumpy tweed jacket.
 I've never actually heard anyone laugh hollowly in real life before. I was quite impressed with myself. It just sort of came out naturally.
