An apology. When I post from work (as with the previous post), I am in a strange limbo, half-in and half-out of Blogger. I can sign in and create a new post, but as soon as it is published I am presented with the sign-in screen again. I can't comment here or anywhere else under my own identity, and I can't edit my own posts. In this limbo, Blogger takes liberties with my formatting (about which I am usually quite careful, as I like to keep the blog looking clean), putting several paragraph breaks on one side of a quote and none on the other, and line breaks in the middle of lines where there shouldn't be any at all. Worse, I can't get back in to edit or correct any of it. The infelicities have to stay until I get home and can access the blog on my regular machine (modest though it is) to put them right.
So if you see a post on here with odd formatting and lots of stupid errors, please accept my humblest, and I will be tidying them up later.
If I am awake.
