Tired

We've been having a little tiff with the upstairs neighbors. A few weeks ago, the girl was pretty drunk and was yelling and stomping around until past 2:30 on a Thursday. Jeremy had to get up at 6, work a full day and then drive to Indiana to get the trailer so we could start Moving Weekend. He talked to her (in person), then when she started yelling again, filed a complaint with the Apt people. Yesterday we got a note on the door sometime in the evening that read:

Stop playing your music/ Surround sound so loud or we will call the Apts.
      Thanks
   Annoyed Neighbor!

I've always felt that, when complaining about noise, a knock on the door works best since everyone knows how loud the music is at that time and it get fixed much faster. We asked the downstairs neighbor about it, and they said that they hadn't heard anything, which makes us believe this is some kind of retaliation. The speakers have spikes on the bottom which attach them to the floor, so if anybody complained, it should be downstairs neighbors. It's kind of mean, but if I meet them (or her), I'd like to ask if she's the one that sounds like an elephant. When the one of them gets up at 2am every night for water and bathroom, they walk so heavily it wakes us up. The first week, I thought that they had put a bowling alley in up there, or that the elephants had already migrated.
