I had a neighbour I lived next to that no joke the kids used to play basketball inside the apartment. We met the poor person below them once and she asked almost jokingly if they play basketball. Yes, yes they do that is what they’re doing.
Luckily at my new apartment I don’t have to wonder what they’re doing because in addition to the stomping I can also hear their kids fucking screaming the entire day. Do they jump on their bed at 5 am? Why yes. Do they chase the dog around at 2 pm? Why yes, yes they do. Does their dad come home and yell at them at 5 pm? Why yes! Yes he does.
