There are instances where one may listen to rechilus although the information is not at all pertinent to him.
When an individual is experiencing sadness or extreme anxiety and is in need of someone with whom to share his frustration, it is considered an act of kindness to lend a sympathetic ear and listen to his troubles. One must be certain, though, that the circumstances do, in fact, demand this. Also, such expression should not become a regular occurrence for the speaker. Finally, care must be taken that the speaker not wander from the matter at hand and offer negative remarks which are not relevant.
One may also listen to rechilus if his intention is to make the speaker understand that his perception of the situation, and of those of whom he speaks negatively, is mistaken.
