It has to take effort to be that loud. What are they doing up there!

I live in a 3 story apartment complex on the first floor and my upstairs neighbors are unbearably loud. I understand that they have small children and that children like to run and play, but this is out of control. It sounds like they are literally beating on the floor half the day. My roommate and I went up to talk to them about it, and while they were very polite and apologetic, they completely insulted our intelligence by expecting us to believe that actually, it’s the people above them making all the noise. Really? REALLY? Not possible. I sleep until 8:30 every morning, but their shenanigans were starting around 7:00 am, waking me from a dead sleep on a daily basis. I finally called the office after losing more sleep than I could handle and they apparently called them. It seems to be quieter in the mornings and late evenings, and I’m gone during the day for work, so I can’t really complain. But one has to wonder… What the hell are they doing up there to be that loud? Mommy must have some pretty good sedatives to deal with it on a daily basis. Maybe I won’t have kids after all…
