I used to have some neighbors who hollared a lot. What a huge nuisance! I think they did it just to clear the smog from their lungs or something, because it was quite regular. If somebody caused me to hollar so much, I would have them in my rear-view mirror, and I would not take one last look before leaving them behind forever.
I do understand your frustration with these loud neighbors. Maybe they do it to distract you from hearing somebody poop, or other noises.
When I had the noise in my life, I found that real dangers, and other things to report to police were done quietly. I never heard those events. The noise was aways just that, noise. My little girl was often a nervous wreck because of all the angry noise. If it was very early or late, so as to interfere with the sleep of some people, and was outdoors, I sometimes stepped out. to say, “Hey, respect the neighbors with sleeping children; lower your voices, or take it somewhere else.” Sometimes I got so frustrated I’d say something like, “Kiss and make up, or kil him so I can call the cops and have all the bodies hauled away.” Mostly I just turned up the tv.
