As the old saying goes, it is better to offend a gentleman than a villain. This is a wise saying to deal with villains in life. A nobody is someone who dares to pay a huge price for the smallest grievance. Even if you win the villain, I'm afraid you will pay a great price in the future.
In dealing with people, we should take a warning. Who knows if there is an ugly heart hidden behind a smiling face, and who knows if there is a conspiracy behind the smiling face. Are there few such stories? Quite a lot. Many people were driven into the land of destruction simply because they ignored those who greeted them with a smile.
