I wouldn’t call it a skill but I’m really mechanically decent (3D puzzles and Rube Goldberg aptitude, that kind of thing), and my visual memory is really good, so I have the uncanny ability to tear apart household appliances, do something else for hours or days, then return and slap it all back together about as quickly with no leftover mystery screws. I just look at the shit all strewn about, and can somehow recall the very last thing I was holding and work backwords
