Oops. Yesterday night's post was accidentally labelled with today's date which resulted in a slightly upset mother thinking I'd forgotten her birthday, especially since it's a big one — err, I mean a special one. I've only had nineteen and a half of those fifty years, but I want to thank her for all of them. To show I'm suitably penitent for the mistake, today's post is dedicated just to the birthday greeting she deserves and nothing else.
