Gossip

What you don't see with your eyes, don't witness with your mouth - Proverb

It's as simple as its said. Don't be a victim of gossip, he-said, she-said.....if you didn't see it happen, don't talk about it like you did. 

Gossip is a terrible act to be involved in because it really diminishes your character and places you in a not-trustworthy category. 

The best way to avoid it is to inform the teller of the "story" - that what you don't know is good and you will like to keep it that way. The more you say this, the less tempting it is for those "story tellers" to bother you with "what's happening now". 

You are responsible for what's been fed to you. If it isn't edifying, then please by all means - keep it moving and if they don't, then you walk away!!
