Although you are a passerby, you are in a similar situation. I understand you. Since you didn't ask anything specifically, I'll follow your thinking. I broke my "sadness" for my father. I feel sad, not only because my father was caught off guard, but also because of him. People still need to work in recent years. What saddens me even more is that he has worked hard all his life. When he stepped into the threshold of "the old man" and counted the gains of this near life, he found nothing! There is no money saved, no hobbies, and it is common to raise adult children! I feel sad that he is at the construction site, and the fields burn his life, just for his children to dress, eat and go to school. I'm sorry that he hasn't found the meaning of life yet, so he will never have another chance. I am very sad that his mediocrity has made his life's efforts and gains negligible.
