One of my neighbours posted this on the wall in the hall of my apartment building. Funny, he puts it up on the wall for everyone to see rather than talking to the manager or confronting the person directly. Lamer. I did get get a good laugh out of it tho. She must be loud for him to hear her, this is a concrete building, and I very rarely hear my neighbours at all unless they are out in the hall talking. I play music and movies quite loud on my main stereo system and I never get any complaints. Maybe I just can't hear them. Ha. Or maybe they're all big Sepultura fans.
Oh, and the picture [in case you can't make it out] is of a guy smashing a guitar against the wall. In case she can't read I suppose.
