I worked with a woman who was a complete hypochondriac. She would come in 1 day with a brace on her right knee, a few days later on the left..same with wrist wraps and other tape.

One day she came in dragging her leg. She told me she had dislocated her shin, and was going to the doctors after work to get a shin splint...

I still can't stop laughing when I think about it..

Not me but some friends of mine.

They bought a house with a pool in the backyard. After a while they became suspicious that someone was using it whilst they were at work so they set up a couple of security cameras. It wasn’t very long before they caught the culprit…… The very old man who lived next door who would appear shortly after they left in the morning, completely naked, equipped with his own inflatable raft and proceed to float around on it for a few hours.

Full karaoke performance… in complete silence… with headphones on (lol)

I once saw my neighbour absolutely belting out what I assume was an emotional 80s ballad, but he had noise-cancelling headphones on. No music audible. Just dramatic hand gestures and power stances in total silence. It was oddly wholesome. Made me realize everyone has their weird decompression rituals.
