Actually, people with strong inner selves may have mental illnesses. The price of emotional stability is not only absolute rationality but also possibly emotional neglect. Because they have never received emotional responses, they no longer expect emotional value from the outside world, nor do they bother to provide value to others. What will they do? They will learn to heal themselves. So when they have the ability to provide themselves with emotional outlets, they are even more reluctant to maintain troublesome social relationships. Some say it's like punching cotton when dealing with such people, but we can't blame them because from the beginning, their emotions have never been understood or cared for by others. They are always self-digesting, so how can we expect them to understand and care about others.
