For me it was the one where the OP was annoyed because she was trying to have a nap on a bench (on her lunch hour IIRC) in her town centre and some kids were being noisy nearby.
According the MN world this is super common and perfectly reasonable and posters do it all the time.
I can honestly say that I have never in my almost 40 years seen anyone having a nap on a park bench during the day.
