I find gossip mind numbingly boring, and it does always occur to me that they must tell others things about me.
The point of gossip is sometimes to build a type of closeness, and most people will spill what they know once the other starts talking about someone (reciprocity).
Here in KY it is the worst I have every seen. I grew up in MI, and good friends didn't gossip about each other to lesser friends, if that makes sense. Here, someone can carry on about how so and so is like a sister to them, best friends for 20 years, then bam, they get you alone and they make snarky remarks about this best friend to you, a stranger.
Last place I lived there were women (labeled "the ladies that lurk" by another woman) who sat outside and stared at all the comings and going. Now, they wouldn't call the police if they saw someone assaulted or saw a drug deal (they might make someone mad at them), but they would run their mouths. I quit a job in a huff after I got grabbed one too many times, was unemployed, yada yada, was selling stuff off on ebay that I needed to get rid of, these women staring, finally one day, they send one over, the "nice" one to ask about the job, the this the that. I was fairly polite, but...
Live by the sword, die by the sword, knowing they all like to yak, when I saw another, less nosy neighbor is the laundry I told her,
"If I ever get to the point where all I want to do is watch other people all day and gossip, I hope someone puts a bullet in my brain."
Sure enough, the ladies that lurk made a point of NOT watching me as I came and went.
Many like to start the gossip as a sort of overture to getting closer, sharing dirt or opinions about others as some kind of bonding thing, more proof to me though that there are many stupid people in the world.
