Bryce and his girlfriend Lindsay are an adorable couple. Need proof? One cozy night in, Bryce had a lil’ bit too much too drink. Unfortunately, the bathroom was occupied at the time, so he booted (adorably) in the sink…which happened to be full of unwashed dishes. The next morning, Lindsay found her favorite coffee mug filled to the brim with not-coffee. The result was Instagrammed.

From a house full of roommates in Texas, our submitter calls this “a prime example of ‘dogs have owners, cats have staff.’”

What’s frightening, of course, is that these things needed to be stated in the first place.

(Thanks to Jill in Des Moines, James in the U.K., and Heather and Eric in New York for submitting…and the kid from The Squid and the Whale for the, uh, inspiration.)

Sarah in Somerville, Mass. wasn’t fazed when she left her apartment one Saturday to find this otherwise “run-of-the-mill your-mother-doesn’t-live-here note”…until she rounded the corner and was greeted by photocopies of the same note taped to every available surface in the hallway.

Then, the next day, another note appeared near the elevator…

…which had apparently been written on the back of yet another (more targeted) note:

“In fairness,” Sarah says, “this whole thing really is gross, and now the lobby and the hallway — in addition to the elevator — smell of vomit. I’m just not sure why the first notewriter thought that spending $10 on copies was going to help.”

And lastly, Sarah adds:  “My mommy didn’t clean up my dorm, either.”

In terms of the appropriate sympathetic nervous system response, an e-mail subject line like “big favor” is kinda the modern cubicle-dweller’s equivalent of “Saber-tooth tiger outside cave!”

(Note: this e-mail, our Seattle-area submitter says, is from the very same person who brought us this.)

Dealing with the rantings of your crazy boss or overzealous receptionist is one thing, but what do you do when your office’s resident passive-aggressive note-leaver doesn’t even work there? Casey in San Diego (a.k.a. RunBarbara) says that’s the situation she’s found herself in at her job.

The offender, Sandra, “has met me a total of twice, both times for less than a minute,” Casey says. Yet for some reason, when Sandra (the aunt of the owner) stops by the office once a week to water the plants and drop off supplies, “she leaves these strange notes EVERYWHERE — and she almost always directs questions about said notes to me,” Casey says. “I often have no idea she posts these notes until someone asks me about the odd directions in them.”

Below, a small sampling of Sandra’s delightfully bizarrre directives. (Just click on the photos to enlarge.)

I’d like to think this note was posted immediately following the “potluck”…

Anna brings us this charitable little note from the her apartment building in London, Ontario.

“Anytime Stan” — proof that Canadians really are the nicest people on earth?

Meanwhile, in Milwaukee…

And lastly, a vaguely dadaist interpretation, in what very well may be another one of L.A.’s elevator-cum-film sets.
