When I posted the details of this lunchtime's bloggo updates to Usenet I did so under the title "Thursday 13th Part One". This evening I received a terse email from Matthew Osborne, pedant of this parish. It read: "You know it is Friday yes?"
It is good to know someone at the CFZ is on the ball. Forget me not knowing what day of the week it is, with a haircut like mine, I still think it is 1972!
