I remember an IQ test I got when they were testing me in 2nd grade and it was to identify everything wrong in a series of pictures and one was about a boy looking in a full-length mirror and when I finally said I couldn’t see any more and called for the next picture he said he was surprised that I had got all of them but the most obvious one, that the mirror didn’t reflect the boy, but I pointed out there were two small diagonal lines on it instead and I said that was a recognized artistic convention calling attention to its reflectivity rather than what it was reflecting, and I kinda wonder how that got scored
