Before we got married my husband and I lived in 4 different apartments all within the span of one year. The worst one of all of them was actually a great apartment, but our upstairs neighbors drove us positively insane. A list of their common antics:
Blasting movies/music with the bass turned all the way up into the small hours of the morning, in their bedroom, which was directly above our bedroom
Stomping, all day, every day, no matter what, always stomping. Sometimes running full speed around their apartment.
It was a 1 bedroom and they had at least 4 adults (two couples) and at least 2 kids living there.
They also always had company over.
It was a nonsmoking complex but they smoked on their porch and tossed their butts over their balcony, which would leave them landing in our little porch. Constantly came out to find butts and trash in our potted plants and all over the ground.
We had to call the sheriff on them once because one of the couples living there got in a very loud, very obvious domestic violence situation. We heard them screaming and throwing each other around. At one point the man smashed her head through the wall.
The kicker was when they brought home one of those mini motorcycles and put it out on their porch. Their porch was made of slatted wood so there were gaps between the boards. The damn bike started leaking fuel (racing fuel no less) through the slats and on our porch (and all over our stuff). Ruined a table, some laundry I had air-drying out there and killed a few of our plants. Not only that but while this was happening they were throwing their butts down onto our porch too. Could have started a fire.
Then there was the spitting. They would spit over the edge of their balcony and we complained so they started spitting THROUGH the floor boards so it was definitely intentional.
I have never experienced a more trashy group of people. So glad to be out of that apartment and away from them now.
