I have been alone for a long, long time, thinking about many things, and when I lowered my head, tears fell down. In my youth, I did not understand much, but now, in middle age, I have grown wise. I have the freedom of the world, yet I am not a free person in this world. Suddenly, I realized that I have no friends and no one who truly loves me. Sometimes, excessive kindness can also be a form of foolishness; remember to reserve your kindness for those who are worth it. My heart suddenly felt empty; it turns out I am so lonely, and in this vast sea of people, I am ultimately all alone.
