Jessica in Portland, Oregon was on her way home when she saw this note taped to her neighbors’ door. “I’m best friends with the guys this was addressed to,” she says, “and they actually are very loud when they get down to business. It doesn’t usually bother me because I work night shifts, but obviously it is wearing down the woman downstairs.”

(The “happy ending”: Jessica says her friends sent a note back saying they would try to be more considerate.)

A few months ago, Christie in North Carolina joined a group on Meetup.com, but never found the time to attend any of the actual meetups. This, it seems, is a serious breach of Meetup netiquette. Recently, the group’s owner did Christie the favor of explaining why she was being kicked out of the group — for her own benefit, of course.

Ashley in Ohio has no complaints about the English skills of her Japanese pen pal, but this “thank you” card left her feeling like something must have gotten lost in translation. “Although I’ve been sending her e-mails and cards for every tiny holiday, this apparently hasn’t been enough to satisfy her,” Ashley says. (Ouch.)

One day, says Nancy in Arizona, her dad was getting in his car during his lunch break from Lowe’s (the home-improvement big-box store), when he found this note tucked into his door frame.

“He was surprised,” Nancy says, but instead of taking the contrarian approach, dear old Dad decided to humor the person and move his car one spot over. At the end of the day, he actually got a glimpse of the notewriter — a “rather old lady” who works as the store’s phone operator.

“We spent a lot of time discussing her possible reasons for wanting that specific parking spot back,” Nancy says — especially given that it doesn’t seem to have any particular advantage over the other 500 or so spots in the lot — but in the end, they just had to laugh.

So, one morning, Emily was riding the train from the ’burbs into downtown Chicago, minding her own business like all the other commuters. All of sudden, she says, “about 10 minutes before we reached Union Station, the woman sitting directly in front of me turned and handed me this note without saying a word.”

Hello, awkward!
