Them upstairs

They have been noticeably quieter of late. However I've noticed something odd. They sometimes play their music aggressively loudly for a minute or so, then turn it down to a decent volume. The same thing will happen again and again during the course of the evening. It's all very strange. At 6.50am today I heard some of that terrible music that sounds like a washing machine from a distance. It wasn't particularly loud, but the aggressive bass made my computer table vibrate, and I could feel it in through my arms and fingers. I wonder if they are testing the residents? I wonder too if the family has a history of antisocial behaviour, and whether they have been billeted on us from elsewhere? These people are getting to be right cunts.
