Sara from Austin writes: “I took my 2-year-old to visit my darling (but travel-phobic) father-in-law. I’ve stayed at his house many times, but not since his girlfriend began living there. He told me to make myself at home and use anything we needed, specifically pointing to the linen closet. There was one bath towel and one washcloth hanging in the bathroom (for us to share?) so I helped myself to more.”

The next day, Sara says, “two brand-new (unwashed) towels were hanging in the bathroom and this note was taped inside the linen closet. The towels I had used the day before were all washed, folded and back in the closet behind the note. That night, we moved to my sister-in-law’s house.”

Shaun in Austin spotted this mysterious complaint in the men’s room at his office. (Apparently all of the males employed there are very, very sensitive.)

If I worked at Steve‘s office, I would definitely be rallying the troops to launch a (non) silent 90° protest of round-the-clock water-glass-filling…and then place “out of order” signs on all the restrooms. (It would be lame, but not as lame as this sign.)

This is not a thing, people! I refuse to acknowledge this is a thing!

One reason that notes of the do this/move this/clean this variety inspire so much ire among recipients is the fact that, more often than not, writing the note probably took more time and effort than it would have for the writer to just do/move/clean it themselves. (But of course, to the martyrs in the office, it’s always about the principle of the thing.) Office kitchens seem to be ground zero for this particular type of pettiness.

At Jacqueline’s workplace in San Francisco, for example, “someone left a clean mug on an empty counter” — an offense that was apparently too grave for one coworker to let slide without comment.

Meanwhile, in Ohio, our anonymous submitter came into work one morning to see this note “on a table with maybe two crumbs on it.” Her solution? “I took the picture, put the cleaning supplies away, and moved the note. Later, I was thanked for cleaning the table.”

S in London says his flatmate was obviously exceedingly upset about his missing can opener. Of course, this being England, the old “stiff upper lip” sometimes still prevails…sort of.

In the office kitchen, expecting your coworkers to wipe up the spatters from their exploded Hot Pockets seems like standard enough microwave etiquette. And a ban on charred popcorn and leftover tuna casserole? Eh, fair enough. But this note — from an anonymous office worker in Baltimore — is the kind of thing that leads to out-and-out mutiny.

UPDATE: There’s a copycat on the loose!

UPDATE 2: They’re multiplying!

UPDATE 3: The meta-madness continues!

UPDATE 4: It continues!

Writes Joe in Denver: “My roommate gets very emotional when someone criticizes him, but will gladly e-mail me or leave notes around the house with dozens of ‘little reminders’” like this one — written after Joe left a broom in the living room overnight.

Amber received this amazing note in an envelope on her doorstep in Sacramento. “I have no idea which neighbor sent this to me, but I can only assume it was the paranoid-looking woman who lives above me,” she says. “But I don’t do drugs. I don’t even smoke cigarettes!”
