I worked as a printer for years. It became second nature for me to align text and photos at perfect right angles to the edge of the page.To this day, I can spot a picture on a wall that is crooked by as little as a hundredth of an inch! And of course, I HAVE to straighten it, even if it is in someone else’s house. To look at my apt, you would think that it is cluttered, but I know where EVERYTHING is down to the last paperclip.
