Buddy of mine had almost the exact same thing happen with Jaws. His girlfriend walked in right at the part where the kid on the raft gets taken and she goes "wait why is everyone screaming at the water" and he had to stop it and give her the whole speech about how it was a mechanical shark that barely worked. Took like ten minutes and by the time he hit play again the mood was totally dead. She still brings it up every summer too, like it's his fault she walked in at that exact second. Pausing a classic at the wrong spot doesn't wreck the movie itself, it just wrecks the night, and honestly the horse head is one of the worst places to freeze because it looks fake as hell sitting there still.

My uncle Ray did body work for 30 years and he told me the same kind of thing back in 2009. I was doing a door on my first truck and he picked up my sanding block, looked at it, and said I was pressing way too hard and moving too fast. He made me slow way down and use lighter pressure with longer strokes. Took me almost 3 hours to fix what I messed up in 30 minutes. He said the paper does the cutting, not your arm. I still hear that in my head every time I pick up a block.
