William in Sydney spotted this note on the notice board of an apartment block he was visiting. If you’re going to tackle a DIY project, I reckon that Saturday morning is as good a time as any, no?

Confidential to the notewriter: As someone who also a) lives in an apartment complex and b) works the night shift at a hospital, I’m surprised you haven’t figured out by now that the world doesn’t revolve around you and your schedule. The graveyard shift is already taking years off your life. How about you do everyone a favor and use some of that sweet shift differential to buy yourself a pair of earplugs?

(Nicely done, Laura.)

Writes our submitter in Colorado: “Last year, a frog moved in to our small backyard pond. Although the sound was soothing and peaceful at first, this year it sounds like he’s quadrupled in size, his croaking now loud and obnoxious. We’ve tried to find the frog in the rocks to move him, with no luck. The kicker? “Apparently, one of our genius neighbors thinks we’re intentionally causing the ruckus with some kind of backyard Frog Noise Machine.”

Writes our submitter in Virginia: “One of my (two) roommates is convinced that someone is sleeping in her bed when she is not here. Even though NO ONE has slept in her bed, angry text messages have been exchanged about these mystery sleepover guests, but (like everything else) she has never confronted us face to face. The other night, I stumbled across this gem on her pillows when I dared to enter her room to turn off the light she leaves on for days upon days.”

Ryan came home from work tonight and found this taped to the front door of his Chicago apartment building.

It could be worse, of course. Adds Ryan, “At least she plays nice guitar.”

As part of a lesson about civic responsibility, many teachers encourage their students to participate in letter-writing campaigns to Congress, the school board, the Mayor, or other public figures. (Thanks to the efforts of second-graders in Mission, Texas, for example, Texans can now proudly refer to tortilla chips and salsa as their official “state snack.”)

Meanwhile, this teacher in Ypsilanti, Michigan enlisted her 18 middle-school students in a cause even closer to home — her home, that is — by getting them each to write a persuasive letter asking her noisy neighbor to curb his all-night partying.

An anonymous submitter in Ann Arbor, Michigan received this e-mail from a guy who just moved into her co-op (“basically a co-ed frat house”) for the rest of the summer. “We’ve tried to reason with him,” she says, to no avail. “When asked why he has to get up so early, he says, ‘I have important things to do in the morning,’ and that’s it.”

The even bigger mystery? Wonders our submitter: “Why, if he needs complete silence at night, did he move in with 16 other college kids on summer break?”

This bit of poetry is brought to us by Alex in Vancouver, an innocent observer on the scene.

One loverly lady in Illinois found this note on the door of her dorm room after a long day of classes. (The identity of the note-leaver is still a mystery, as is the meaning of the phrase “dollar sign flower slams easily.”)

Adds our submitter: “When we had our next floor meeting, I did the not-so-passive thing of calling out ‘whoever wrote the note,’ saying that we were trying our hardest to keep her ‘lovely.’”

Cassie in Orlando is a preschool teacher, and brings us this note posted by the school’s director. “I cannot help but be in awe of her after this note,” Cassie says, and I have to agree.

A classic, no?
