I see what you mean. Maybe these people aren't really aware of the impact their behavior/actions are having on their own system and welbeing? Personally, I realized when I was at my most obnoxious, it was due to a profound disconnect within myself. The more you understand how you're impacting yourself, the more mindful you become, so maybe these people aren't setting out to bother, but are just...disconnected? :)
I think if these folks are used to city life, they don't hear how disruptive the noise is.
You only hear the noise when you understand the quiet. I hope your week has quiet :)
