Stuffing your neighbor’s mailbox with a bag of dog poo/a dead rodent/a hundred boxes of orange tic-tacs? So amateur. If you really want to drive someone crazy, try repeatedly scratching out her name and writing “VACANT” over it instead. Apparently, it works like a charm.

Before her husband left on his first military deployment, Sarah in San Diego sent out an e-mail to the whole family with info about how everyone can stay in touch while he’s away. To avoid any potential in-law drama, she even had her husband read and sign off on the e-mail before sending. What neither Sarah nor her husband took into account? The Uncle Paul factor.

Her husband’s Uncle Paul, Sarah explains, is a mailman/postman/letter carrier — whatever the correct term is. (Based on Uncle Paul’s reply, she says, “I’m clearly not up enough on the intricate etiquette of the U.S. Postal Service to know.”)

If you’re one of the poor sods charged with delivering catalogs and promotional flyers across Australia, it seems like the job is really a lose-lose.

You’re either lazy, as witnessed by Stacey in Brisbane…

or, as noted by Briyah in Sydney, you’re an illiterate prick.

It all started when Erin in Toronto sent her uncle a Christmas card. Actually, scratch that — it all started three years ago, at Erin’s wedding, the last time Erin actually saw her uncle in person.

Before the wedding, Erin explains, “Linda (my uncle’s girlfriend) RSVP’d that she’d attend, and then then didn’t bother to show up, meaning we had to pay for her meal anyway.” (Not that she’s bitter about that or anything!) “Since then,” Erin says, “I assumed they had broken up and have addressed the annual Christmas card to just my uncle and cousin.”

Now, while that might sound a bit hasty (or even, dare I say…passive-aggressive),  in Erin’s defense, the Christmas cards she received were only signed by her uncle and cousin — this year’s included. And yet, in what appears to be a last-minute back-of-the-envelope calculation, “Linda chose this year to remind me that she was still kicking around,” Erin says.

On the flip side of things, receiving mail addressed to one’s ex can be a disturbing experience as well. I’d say this intercepted message speaks for itself.

“We custom-ordered some stamps with our youngest daughter’s face on it to mail birthday party invitations,” writes Pablo in Virginia. “There were extras, so we used them to pay some bills.” Apparently, one of those envelope recipients found this small act of thrift somewhat less than adorable.

Adds Pablo: “The creepy part? This note was deposited in our mailbox anonymously, making us think the real crazy person is the author.”

Writes Desiree: “This is a note at the express (stamps-only counter) at a very busy post office in Washington, D.C.. They are apparently!! very!! uptight!! like everyone else in D.C. (myself included)!!”

Meanwhile!! in Florida…

And! in Los Angeles!
