There are two situations. One situation is that he has a secret that you don't know, and this secret cannot be discovered by you. So I will deal with his secret at this time. What about another situation? Boys have a relatively closed personality.

If others see a selfish person helping others, they will find it strange and incomprehensible. Therefore, a person's attitude toward reality developed in long-term social life is closely related to his behavior and is inseparable.

Character is gradually formed in the practice of social life. Once formed, it is relatively stable and will manifest itself at different times and in different places. However, the stability of a character does not mean that it is immutable, but that it is malleable. After a person's personality is formed in his life, major changes in his living environment will definitely bring about significant changes in his personality traits.

Definition of character

Character is a person’s personality characteristics shown in his stable attitude towards reality and his habitual behavior corresponding to this attitude.

Attitude is a person's tendency to respond to people, objects or ideas. It is acquired in life and consists of three factors: cognition, emotion and behavioral tendencies. A person's attitude towards reality is reflected in what he pursues and rejects in life, that is, in what he does. And how a person behaves shows how he behaves. A person's stable attitude towards reality determines his behavior, and his habitual behavior reflects his attitude towards reality.

Attitude determines the behavior. A stable attitude makes the behavior suitable for this attitude slowly become a habit and manifest naturally. It is a characteristic of a person's character that he enjoys helping others. He will not hesitate to help others when they encounter difficulties. When others see his helping behavior, they will find it natural and in line with his personality.
