At lunch yesterday I went to a reception at Rhodes House for the Australian Governor-General, Quentin Bryce (presumably in the UK for some minor ceremony or other). This was quite fun once some people I knew turned up, though as always I felt like an impostor when wearing a suit and tie.
One person I talked to was a colleague of Camilla's, John Finney - it's always a good conversation starter when you've read someone's latest paper ("An efficient record linkage scheme using graphical analysis for identifier error detection"). Another was Yasmin Haskell, who I recognised from when I studied Latin twenty years ago. She is a visiting fellow at Christchurch (so a temporary colleague of my sister's) working on scientific poetry in neo-Latin (PDF).
And in the evening Camilla and I went to listen to Colin Dexter (of Inspector Morse fame) talking at the Pegasus Theatre (which is just around the corner from us). He's a charming man and still at 80 a great raconteur and entertainer. He talked more about the television series than the books, but that was ok as Camilla and I have been working our way through the tv episodes. (I hadn't realised that the later books were written after the television series had started.)
Update: some photos of the GG walking through Oxford can be found on Oxford Daily Photo.
