Hey Pandas, What Is A Pet Peeve That Makes Perfect Sense To You As The One With OCD, But Others Find Odd?

Keeping pets.
Wearing shoes indoors.
Not changing your clothes or showering when you come home.
Not cleaning groceries before putting them away.
Dining out during the pandemic and blindly trusting that cutlery and drinking vessels have been cleaned properly.
Sharing towels.
Sharing toothpaste (the end of the tube may still touch the brush)
Putting your belongings on the floor whilst out.
