Can only say that everyone's personality is different, as well as personal cultivation and quality! Besides, he may have some ability. The manager needs his help in some things, but he doesn't mean to be afraid of him or him. Not everyone's personality traits are like that. Some people are good people and some people are bad people. Some people just don't care about others, and it is possible to feel tired. So don't study too much, because of personal character, some people take themselves too seriously!
