Exhibitionism or Over-sharing

I have a pet peeve...well I have a lot of pet peeves actually, but one that I am feeling the need to point out right now.

People OVER-SHARE information about their lives that no one wants to know. Going far beyond and away from sexy exhibitionism. It doesn't matter how polite they are about it, nodding and smiling and "Oh yeah"ing to it because they are too polite to say "shut the fuck up!" They don't want to know, I don't want to know, your family doesn't even want to know.

And yet there is a constant bombardment of TMI around, especially on the Internet. I don't get it! What is the obsession people have about sharing things best kept to themselves? Whether with a stranger or a family member, KEEP IT TO YOURSELF!

I am okay with exhibitionism, I am okay with voyeurism. A fan of both actually. What I am not okay with is the over-sharing of your disgusting human plights of sickness and detailings of such. What is the point of that?

Am I the only one who has found this a disappointing advancement of society? I am unimpressed with humans, yet again...
