Neighbour's 'sex in the building' note receives surprise response

A neighbour's "sex in the building" note has received a surprise response after being shared on Facebook.

The note is addressed to a couple who seemingly enjoy loud sex, with little thought given to those who can hear them. A copy of it has been shared on the 'Bondi Local Loop' Facebook page by a building resident.

The note reads: "When you have sex, keep the noice [sic] down. we hear you and the neighbour buildings."

It ends with the cryptic phrase: "Sex in the building."

While many Facebook followers sympathised with the note's author, others shared a surprise reaction.

"What say to that?" one commented.

Another said: "I couldn't get past the grammar to fully enjoy this."

"You should post it in a Facebook group so everyone knows you're getting a bit," said another. "It's noice."

Notes warning neighbours over loud sex are commonplace in cities where much of the population lives in cramped apartment buildings and unit blocks.

Earlier this year a resident received a note informing them their sex sessions could not only be heard, but could also be seen.

A copy of the note has been shared by the woman's friend on Reddit's 'Funny' thread with the description: "My friend got this concerned note through her letterbox this morning."

"Dear No. 40. I'd imagine you value your privacy in those rather intimate moments in life, but can I humbly suggest that you make extra preparations to ensure your silhouette is not projecting through your curtains showcasing 'the grand finale'," the letter read.

It was signed, "Kind Regards, a thoughtful neighbour."

"Yeah a heads-up is usually welcome. Once had a neighbor with benefits and she was mortified when I told her I had seen her nude before our first time cause of the s---ty windows/curtains situation.. but it just happens, accidentally," they wrote.

"It's very nice to take time and let someone know! Unusual, even."

Another commented: 'My curtains are really sheer too. I couldn't be bothered to change them, though I should."
