Checkmate
Susan, there’s no need to take everything so literally. This probably started with one person who thought they were being humorous (and they were right), setting off a chain reaction as everyone wanted to join in the fun.
We’re left with two questions: Why did someone mark an X? And even more baffling, what does that winky face signify? Did they or didn’t they flush? Even when the sign isn’t overtly passive-aggressive, it doesn’t mean you can’t be!
