My neighbor is outside loudly complaining to her daughter that nobody in the apartment complex says "hi" to her. They just give her dirty looks.
This is a woman who has harassed my girlfriend and I (both very quiet people who sit at our computers all day) with numerous noise complaints. I've heard her boast about filing complaints and calling the cops on people. She makes me constantly afraid to do anything in my own home.
"No such thing as common courtesy these days" replies her daughter.
