i see both sides, having lived with both super sensitive and petty neighbors, and also inconsiderate, loud neighbors.

There are definitely sensitive people who have either misophonia rage, or PTSD from something, and they can't handle normal levels of city noise.

on top of that, some apartments simply allow smoking inside. If they always use the balcony, they're really doing you a favor.

if you are worried about emissions, you really have to think about cars and refineries and jets, and even restaurants. These are incredibly out of control when it comes to pollution and disease.

in my experience, if you're buying machines and building devices, and your target refuses to play that game, then it's clear who the adult is, and who the child is.
