Something in my brain broke in the past year and I can’t see typos anymore. It worries me and I delete more tweets than can be counted. It’s not the words that disappear, but for so long I could find a misplaced comma in a textbook and now that sensation of spotting has diminished. Odd to be an editor now and not a line-reader. Larger screen, daily glasses, yes. But also the shame of so often mis-speaking in public; seeing only the mistakes and not the intended thought.
