We should have a good opinion about othersI don't think it is a big issue if people have the wrong opinion about me. We can't stop people from having any opinion about us. Do we not ever have a negative opinion about someone without knowing the reason? Probably, we also have this bad habit. Nobody is perfect. We don't know what trait or activity of ours annoys other people but they never tell us. Do we ever ponder over this matter if any of our activity disturbs other people? Sometimes, misunderstanding between spouses destroys their family life. It may be observed that siblings also become enemies because of misunderstanding.
If you have any complaint about any person confirm it directly to the concerned person. It is my habit. If someone tells me about any person something negative regardless of who the informer is I don't trust until I get it confirmed from the concerned person whose complaint was made about. I have noticed that people like this way of knowing reality about the matter.
