For the past few years, I've been really bothered by the fact that a family member constantly tells acquaintances things that are non of their business and exaggerates problems so that people think we are completely ignorant and incompetant.

I started thinking about this because a series of older narcissistic men started regularly butting in and trying to take over our lives and kept saying we can't make decisions without them. And it took me years to figure out that my sister was inviting this by oversharing and exaggerating things to virtual strangers. She even gave our home address a violent man who stalked us for a year (he claimed to be worried about us).

One time, we had an attempted burglary that failed. The police had actually surrounded our house before we even knew there was a burglar and caught him within seconds of us first seeing him. My sister posted about it on Facebook and told everyone we met for years that people regularly try to break into our home. And that has caused several horrible creepy men to keep saying we can't live without their protection and advice and keep hounding us.

And it happens with many other aspects of our home life. My sister is quick to declare our belongings defective or things we do to be failures which makes everyone she talks to think we are incompetant. I know oversharing is a big problem nowadays in families. It's just worse when the oversharer is a pessimist so everyone thinks the worst about things that are not really their business.

I've learned to be ruthless about shutting out the meddlers as soon as they get intrusive, but its just so annoying to have this stream of distorted information going out all the time. Many times I have had to tell my sister to stop giving out information about me and household finances to men who behaved as if they had intimate relationships with one or both of us.

She's just compeltely clueless, chatting on and on with a creepy married man until I showed her evidence that he had been accused of being a serial rapist (that's one of the men she gave our home address to). Is there an obsessive compulsive blabbing disease?
