A few days ago, I ordered two things from the amazon.co.uk marketplace (i.e., from private sellers working through Amazon): the recent biography of Stanley Milgram (that's the psychologist behind those obedience experiments and the concept of six degrees of separation; it seems like a very interesting book), and a copy of Belle & Sebastian's Legal Man single. I was expecting at least one of them to come in by Saturday's mail*. Imagine my surprise when, upon coming home this evening, I found that both items had arrived.
* for the Australians, there is postal delivery on Saturdays in the UK. It sort of makes up for the total lack of trains on public holidays.
