I lived in an attached townhomes (moban) that belonged to my gf. We had 3 main noisy neighbors, next to us and 2 opposite. They had party a least 3 nights per week. Our small garden at the end of soy was toilet of next door guests. I complained 2 or 3 times, but I only received worse. I was totally disappointed and could not see any solution till Covid began.
The next door Mr brave man lost his job after years. Sitting home most of time. His aggressive wife worked only and at this time they were not so brave anymore.
opposite neighbors, both lost jobs. One drove a MB to work, but now had to get a cheap job and got a cheap small motorcycle. The other opposite neighbor (coyote laud sounds at 3:00 morning) started a food business by his gf (abusing her in fact to save the house from bank). It did not take too long and he sold the house for cheap to avoid foreclosure.
I moved out before I could see all what happened to them. I'm sure they never change and do the same when they rise again.
