Them upstairs

They have behaved disgracefully all weekend. Apart from being woken up at around 4am on Sunday morning (again), there was the most terrible noise on and off all Saturday evening and night, and again on Sunday morning. Earlier on this morning I got an email from the tenants' association saying that another neighbour had complained about them. I'm glad about that, because if I'm the only one to say anything, it could look like I've got it in for them. The tenants' association is very good. They won't put up with this sort of stuff, and they have told me what they had already done and what they are going to do next. All the antisocial behavior hit me very hard over the weekend, and hasn't helped  how I've been feeling.
