A dying breed of neighbor

I have found out this week that having a dying neihbor is having a pretty rotten neighbor. The Chinese couple downstairs (the same ones who broomesticked my bird feeder/hotel into oblivion) use to fight alot and there would be lots of screaming, back and forth, ya ya ya. Then it stopped for a few months and just this week it has gotten crazy again. The old man is dying and his wife is not taking it well. At least an hour a day she just wails as loud as she can stomping her feet and then spurts of running while stomping all at full lungs and full speed. They live below us and when she has one of these bouts the floor shakes so much it becomes crazy annoying but how do you tell your half dyinging chinese couple to please quite down while I play on the Internet please. Even though he would never smile at me, say hello or even acknowledge my presence on the stairs its too bad he's dying.
