Gossip

Donna has not yet met Barb.

If Mary paints an ugly picture of Barb to Donna,

then Donna will likely

form a bias, dislike, avoid, repel, reject Barb.

Reputations can easily be destroyed. 

That is slander.

Words can destroy reputations.

Great minds discuss ideas.

Average minds discuss events.

Small minds discuss people.
