because I will gain nothing if Insult you, but If I tell you good things then you may get benefit and others right?
See phoenix2009 here and in other places there are some people who think that if people are speaking about some one then they are speaking about him.
For example Olive speaking with Saggi about one miser person and there was a person nearby listening, the person might think they are speaking about him.
Now imagine that this person is really miser what he might do? He might say bad words or do other things, but if this person is not miser and confident then he will not care about Olive and Saggi are saying because he knows his self very well.
