When Twos, Threes, and Fours are well-rounded, highly functioning, psychologically healthy people, their particular sensitivity to feelings helps them form solid, functional relationships. In fact, they tend to be more concerned about their relationships than the other types. Even though they may feel things more deeply than other types, they also tend to have more difficulty when it comes to relationships. When Twos, Threes, and Fours lose it, or become pathological, their emotions go haywire, approaching volatile, unmanageable, oppressive, and imprisoning.
