“If it wasn’t for the handwriting,” says Lauren in California, “I would have guessed my mom wrote it.”

Meanwhile, Carson in Valencia found this note (crudely laminated with packing tape) attached to a tree while walking his dog in the park. “Maybe next time Maggie will think twice about leaving her ceramic cats unattended,” he says.

And in Seattle…

“In the pot-snatcher’s defense, people leave furniture and the like on the street all over this area of town as acts of charity, so it definitely would have been an easy mistake for anyone to make,” Josef says, adding: “When I took this picture, the homeowner was glaring at me from the garage the whole time.

This note from a “friendly neighbor” was put through the mailslot of Dan’s apartment in the heart of South Philly. Says Dan: “I wanted to put ‘thanks for the advice!’ on the door in response, but thought better of it.”

The word “newsflash,” like the phrase “no offense,” is an early indicator that what follows is probably going to be something pretty bitchy. Unless, of course, you’re watching TV news, in which case the word “newsflash” more likely heralds the announcement of a hard-hitting segment about the household product in your kitchen that could be killing your children.

Exhibit b) from mother to daughter, Irving, Texas

Exhibit c) the pointed use of song lyrics in a Facebook status update

Exhibit d) stating the obvious

While other passive-aggressives plow through post-its with wild abandon, the caretaker of Kale‘s building in Winnipeg has a more economical style.
