From my experience i have never met one person in my life who didnt do it. Not even one time.


My family (mostly the adults) does it all the time. My aunts will talk crap about my grandmother, my mother will talk about my father. I stay as far away as I can from that. Which is why I do not voice my opinion about anyone in my family.

But I have very good friends, and only very good friends. So we don't have anything to say about each other that we don't already know about each other.
