It was when the kind reader pointed out to me that not only had I misspelled Matthew Zapruder’s name and that of his book (which, frankly, looks alien to me in any possible spelling), but that I had also misspelled the title of my own book, that I had to concede that this here bronchitis is taking more of a toll than I’d care to admit. I’m going to give it a rest for a few days and see if I can’t push my IQ back up to a dull normal.
