The human heart is complicated, just like a script. Sometimes the author is the protagonist, sometimes the villain, and sometimes the supporting role. 2. To understand a person is not through one thing, but through one thing and one thing. The human heart is unpredictable. You will never know how complicated a person is. You will never know how sincere a person is. You will never know how hypocritical a person is. It's not easy to see a person clearly. You need time, you need to observe, you need to get along, you need to believe, you need to see through, you need to identify, you need to judge. Sometimes you have to believe that some people are deliberately trying to make you unable to see through, deliberately making you misunderstand, and deliberately making you sad.
