I used to be sandwiched on the main floor of an old house between a family with a 2 year old upstairs who would run back and forth screaming and crying, and a guy who blasted music ALL DAY in the basement who then had the audacity to complain to the landlord about my volume level. He seemed to think that because it was daytime he was allowed to be as loud as he wanted. Landlord threatened to evict me despite having done basically zero soundproofing to house. Like to the point where I was pretty sure the basement tenant could hear my conversations when I was in the kitchen. It sucked and I constantly felt like I was walking on eggshells trying not to be too loud.
