I suffer death by presentation for the first half of a day: over four hours of watching vendors show off their products. The presentations are perfectly engaging, and there is both morning tea and lunch, but sitting in a hard plastic chair for half of the day virtually kills me. I am a slothsome wreck for the afternoon. Today is definitely a reminder of exactly how tiring a simple day at work can be.

We have pizza for dinner and then sit down for The Empty Hearse. I love this episode, and the way it neatly bypasses providing a complete and authoritative explanation for the ‘fall’. I also love the cheeky way it manages to nvlude the various fan theories. I’m surprised when I realise that it’s written by Mark Gatiss, rather than Steven Moffat–it seemed far more Moffat’s style.
