They are not "awful people". You chose to live in a multi-unit apartment building with balconies close to windows, where so many neighbours smoke on the balconies that there is _always_ someone smoking close enough to make your apartment smell disgusting, then you judge them all as if they knew how much gets into your home and how sensitive you are to it. Instead of proposing an hourly half hour no smoke compromise on the next meeting of the building's co-owners, you just declare them awful people just because smoking is part of their lives. They live in a city and can't "just quit". That doesn't make them awful people.

Tbh, I'd rather live with most of them than with you. Since they smoke on the balcony, rather than near roommates/family, many are likely more mindful and pleasant to coexist with than what you displayed.
