About 12 years ago, one of the Karens pushed all the wrong buttons and got me annoyed in her general direction.
I’ll skip the details as there were (somewhat) innocent third parties involved, but suffice that it wasn’t the sort of thing you end a friendship over (We still exchange Christmas cards to this day). But some sort of response was clearly called for.
Several days later, Karen received an unexpected package in the mail. She recognized the return address as mine, but didn’t think about the implications. My planned revenge went even better than expected when she opened the package while sitting on her bed. (Silly girl, she should have known better.)
That evening, Karen had to explain to her husband how it was that their bed came to be full of birdseed.
