I apologise to those of my readers who have been plagued by the fact that a talk I gave about my grandfather Hubert a month or so ago always appeared first, as if I hadn’t posted anything since. This was a glitch in the system, owing to the fact that I must have pressed a button marked sticky and its stickiness meant that it always appeared on top. But I have now managed to rectify it, thanks to admirably clear instructions on Google, in order the resume normal service.
