There’s a Hebrew saying – “If someone is gossiping with you, he’s gossiping about you, too.” Which is probably correct. That’s why i hate listening to gossip even passively.
But there’s also another thing. Some people like to gossip about other people, and in the same time, either deliberately or compulsively, live their life in such a way that other people can gossip about them.
When i try to think logically, then the idea of gossip is supposed to be this: When you say unpleasant things about other people, you are supposed to imply that you are not like that. But that thinking is too naïve and positive – quite often the opposite is true.
