We're going in to talk to the resident manager on Monday (this is Vancouver, WA by the way). We're going to file a harassment complaint with her regarding our neighbors and claim that we are at a reasonable noise level between 10PM-8AM.
They once said our TV was too loud so the resident manager came over & did a sound test to let us know where a reasonable level was. I mean, we've been way too accommodating as is. Funny enough, she could barely hear the TVs because of how loud the kids were downstairs (It's a big Filipino family).
This resident manager once hung dog crap on one of my neighbor's door because she thought it was their dog that pooped in the common grass area. She's not all there.
