There is no perfect person in the world, so we should not talk about other peoples shortcomings or expose their privacy, which not only hinders others reputation, but also indicates that you are despicable and that others are unwilling to make friends with you. First of all, we need to understand that what we know about other people is not always reliable, so when we talk about it, we may turn black and white upside down. The relationship between many people is very complicated. If you dont know the truth, dont talk about it, or it will cause tragedy. Most of the time, we should be silent when talking about others doesnt help us but hurt others. Even if we overpower each other with arguments, we hurt each others self-esteem and their hearts hate us. It also shows that we are uncultured, easy to develop the shortcomings of pride, will lose many friends, and will be blamed by everyone. In my opinion, if there is no real ability, there is no sense in hurting others by talking, which will not make them appreciate themselves.
