I used to live next door to a perfectionist.
God love him but his life was a misery! Anything that was remotely out of kilter had to be adjusted immediately. His asphalt driveway had to be given a regular coat of black paint to hide oilstains, all the screws in his constructions had to have their slots perfectly in line and he even had a template and spirit level for cutting his hedges so that the sides were vertical and the top horizontal and perfectly straight.
I thought he was the winner, but not so.
Recently my Linux had an update. It was the package that contains all the background images, or wallpaper if you prefer. There are 23 photographs in the package but one of them had been changed, apparently after a complaint from a user who must be the winner of Perfectionist of the Year.
This is the image that was updated, with the original on the left and the updated one… well you can guess! Clicking either will enlarge [they are quite big].
Can you spot the difference? Believe me, there is one.
It took me an age to find it.
