Philosopher: Well, I'm going to ask you the other way around. Why do you so stubbornly claim that people can't change?

Youth: This is the reason. One of my friends is a man who has been hiding in his room for many years. He really wants to go out and have a job like a normal person if possible. He really wants to change his current self. As a friend, I can guarantee that he is a very serious and useful man to society. However, he was very afraid to go out of the room. As long as you step out of the room, you will immediately have palpitations and trembling hands and feet. This should be a kind of neurosis. Even if you want to change, you can't change.

Philosopher: What do you think is the reason why he can't go out?
