London tomorrow, teaching people to memorise the locations of Christmas products in Sainsbury's. Rather than preparing my presentation, I've spent the weekend watching the Alan Bennett season on BBC2. This is justifiable, you see, because Sainsbury's is mentioned in passing in "A Chip In The Sugar", which was on today. However, the practical upshot of this is that I'm only just now finishing the tedious preparation work. This is a really good example of why people who say I should do memory stuff for a living don't know what they're talking about.
