Allie in Ypsilanti, Michigan was walking into her local Target store when she noticed this little art installation on the sidewalk outside. Granted, she says, “The closest Wal-Mart is about two miles away, and I have no idea how the cart got there either.”

The chalk artist had also drawn purple arrows across the parking lot in the direction of the Wal-Mart, and while Allie says she didn’t check to see if the chalk lines extended all the way to the store, “drawing the arrows but not taking the cart back would have been pretty P-A.”

Meanwhile, Michi spotted this piece of guerilla knitwork chained to a post near NYU. (“It was, on inspection, empty.”)

Mim decided to take a back road to a friend’s house in Wisconsin when she spotted this sign in someone’s front yard — presumably, she says, a reaction to the two large silos that were recently erected in the corn field across the road.

At Summer’s office in Austin, there are a few known “soakers” who constantly leave their dirty dishes in their sink. Apparently, the office soothsayer has had about enough of this practice.

P.S. I kinda have a crush on this sign.

Hollie in Portland, Oregon spotted this note on the second-floor landing as she was walking up to her apartment.

While I’m usually not in favor of note-leaving when a direct confrontation would do, I give this one a pass — creative spelling and all — because, really, have you ever met a middle schooler without an an attitude? I’d say forcing a kid to make it through eighth grade is enough of an ass-kicking already.

Writes Elizabeth in Massachusetts: “My dad has taken to mixing hummus and tabbouleh in a bowl and eating it like that, which some reason, drives my brother absolutely crazy. I looked in the fridge today and was not surprised at all to find this note, which my dad ignored.”

Something tells me Elizabeth’s brother might also have an opinion about whether toast can or cannot be refrigerated…and perhaps the appropriateness of Cinnamon Roll Casserole as a workplace snack.

J.T. got a kick out of this permission slip, which his co-worker had to sign before her 17-year-old son was allowed to go the first high school dance of the year. (Apparently “leave room for Jesus” just doesn’t cover it these days.)

I’m loving the concept of “dance detention,” but the name of the high school is really the cherry on top.

Writes Leslie in Richmond, Virginia: “The note’s creator seems to have purposely made his/her community note as undecorative as possible, but left the USA sign, flag, toadstools, ceramic rabbit, and rainbow-colored pinwheels untouched.”

Personally, I would have liked to see if adding of few of these to the yard would have solved the problem.
