Buses

Buses confound me - I understand entirely how you get none for ages and then three at once (it was explained on Notes & Queries once), but I can't for the life of me figure out how you can get none for ages and then just one come along. Where have the other ones gone? Perhaps buses travel at relativistic speeds, meaning that although the time between them is always fifteen minutes from their point of view, more than half an hour elapses for those of us hanging around in the cold for the next one?

Of course if that were the case then you'd expect to get home really, really quickly - at least as far as your house was concerned. But my house agreed completely with me when I finally got back this evening that the time was: far, far too late.

So I reckon someone's stealing Cambridge's buses. If found, please return, etc., there's a good chap.
