If people are willing to confide in you does it mean you are trustworthy, or does it mean that you are known to be a receptive audience for gossip?
The answer depends on the nature of the information confided. Gossip is a sin that takes two: a talebearer and an audience. Do you claim innocence if you assume the passive role and merely listen? This is as essential a part of the process as the one who speaks. Do not be proud that you were selected to partake of this. Have you ever learned things you wished not to know? You cannot receive an evil report without being affected by it. Walk away for the sake of your own purity.
