I used to have a lady I worked with who was like this. She had the common sense of a fucking carrot and was dumb as shit. What was weird is she was highly skilled in the one job she was hired for, the rest of the time she would click on everything and I would had to fix her computer multiple times a week. One time I tried to walk her thru something on the phone and I told her to click on an icon, her response was “Whats an icon?”
