Noah in Richmond, Virginia spotted this earnest plea in the bathroom of “a funky little coffee shop” on the Outer Banks of North Carolina. “The sign was also on a bulletin board in the middle of the shop as well,” he says — “just in case the thief was avoiding the scene of the crime.”

And if you doubt Edie’s ability to get aggressive on your personal-art-piece-thievin’ ass, just wait ’til she catches you in the act. We’ll see how your bathroom art collection looks when she’s through with you!

(I’d like to imagine the follow-up note going something like: “Damn it, Edie, no one wants to see your ‘personal art pieces.’ For the millionth time…FLUSH!“)

On a lark, Michelle in Florida posted a profile on the online dating site OKCupid after taking one of the site’s quizzes late one night, allowing the site to pull most of her interests and whatnot from Facebook.

“I didn’t think anything more of it,” she says, that is, until she got this “helpful” message — apparently one adjunct university professor’s idea of a charming conversation starter.

An eagle-eyed substitute teacher spotted the work of this precocious young propagandist-to-be at a Pennsylvania high school. (Psst! Philip Morris? R.J. Reynolds? Are you paying attention?)

One day, Mike in Seattle pulled into his section of the parking garage, where there were dozens of open spaces that never fill up. “Rather than doing a 12-point turn to get right next to a concrete column, I just pulled in and called it good enough. Apparently I had been taking liberties with Mother Earth that day or something, as I was later blessed with this gem tucked under my wiper blade.”

Trix says her Dad spotted this variation on the same theme while strolling through Portland, Oregon — “a well-known haven for parking-space-hugging liberals.”

And of course, the irrational assumptions go both ways. Amber in Whitinsville, Mass. — who happens to be gainfully employed, thankyouverymuch — found this under her windshield wiper one day.

Lara in Arlington, Virginia bore the brunt of an even more retrograde brand of passive-aggressive paternalism when she committed the sin of parking a smidge over the yellow line.

Diaries, people. Pen and ink. Lock and key. Not on the Internet for everyone to see (and cringe over)!

“During the past few weeks, our  preschool-aged son has been trying to play games that are too violent for his classmates,” Juli says. “We’ve been trying to work on the problem with the teacher, but each morning’s drop-off has become a guilt and angst-filled time for me, in part because I can tell the teacher is trying to be nice but is so obviously annoyed by my child that I can’t control!”

(No need for siding with “team preschool teacher” or “team mom,” here — this kind of relationship is just emotionally fraught no matter how you slice it.)

And of course, the guilt doesn’t stop there. Jennifer in St. Cloud, Minnesota, found this note in her son’s lunchbox (along with most of a ham sandwich).

Explains our submitter in New York: “This note is the result of a less-than-enthusiastic holiday food drive. Our office is a gray, lifeless place — what can one expect?”

(I don’t know…maybe some munchkins now and then?)
