Ugh...well, I called. The gal I got said the policy is to call the police directly. That isn't what the lady at the office said. I'm confused.
Of course, part of that might just be the hour.
Calling the cops is another thing entirely. Man...I just hate this whole thing. I just wanna live my quiet little life, darn it!
However, I sympathize with your desire to not make waves. It's probably going to be difficult to get the office to do anything constructive about it over the weekend, but Monday morning you can go down to the office, see if they'll put a note on the door. It might just be a misunderstanding --- he may not realize how loud his music is.
Still ... Rosie, if someone doesn't call somebody, it likely won't stop.
If you have a video recorder, or a cassette recorder, tape the sound, so you can take that to the office.
