Gossip has ruined countless relationships and has put enmity between many friends. It's a very destructive method of coping with anger, frustration and misunderstandings.
So many problems could be alleviated if people chose to do the right thing. This would be to ignore any misgivings you have about others and try to replace them with nice thoughts. Unfortunately, some people, instead, follow up on their suspicions with unkind talk.
If someone has done something to offend you, a much more constructive approach would be to speak to that person directly. Often, the matter can be cleared up then and there.
