Youth: I'm not sure about the details. Maybe it's because of the discomity with your parents or the trauma of being bullied at school or in the workplace, or because you are too spoiled. In a word, it is not convenient for me to inquire about his past or family situation in detail.

Philosopher: In a word, your friend has some psychological trauma or other reasons in the past. As a result, he couldn't go outside. Are you trying to explain this?

Youth: That's of course. There must be a reason before the result. I always find him a little strange.

Philosopher: Well, let's assume that the reason why he can't go out is his family environment when he was a child. Suppose he grew up under the abuse of his parents and never experienced the true feelings of the world, so he was afraid of socializing with others so that he closed the door. This situation may exist, right?

Youth: It's very possible. That should cause great psychological trauma.
