There are no thrills, no ups and downs, just like each of us in life, there are no great joys or great sorrows, only our own small emotions and thoughts. Those people and things we have experienced, maybe even we forget to ignore them when we are busy, but in the dead of night, the scenes reappear, beating every nerve of us.
In fact, every one of us is selfish and self-centered. Don't think about how good we are. We are all despicable, but the expressions are different in different ways. And we always beautify ourselves and vilify others inadvertently. When the past is clear, do we regret it? About those friendships, family relationships, and love, who have we hurt, and who have we hurt? In the end, after time is buried, only we can still vaguely remember it.
