When I went out into the corridor on my floor I could hear my neighbours music much clearer and... HER SINGING!!

Live and learn lol

Yikes... reminds me of the short time I lived in student housing and felt depressed most of the time. I used to sing and 1 guy confronted me as I was coming in and he said, "So, you're the guy who sings all the time." Oh man, I was so embarrassed. He didn't seem like he was a fan. I guess I didn't realize how thin the walls were.
