A man has taken to Twitter to share a "mortifying" note he received on behalf of all the neighbours in his apartment block.
Stephen Cunningham, 28, had come home to find a handwritten letter was slid under his door from an anonymous resident who begged him to "keep the noise down at night".
While the note didn't specifically say "sex noises" it did say the apartment complex didn't want to be sharing his most "intimate and private moments".
"Just a friendly note from your neighbour to remind you the walls in these buildings are thin and sound can travel," the note read.
"While we appreciate that it is inevitable that we will hear neighbours at times, we want to make you aware that we can hear more than we should.
