Both find in each other the reliability, empathy, cooperation, solidarity and generosity that make them feel safer. They have the same coping strategies, and before they build their confidence, when they test themselves, they know how to respond with a lot of confidence when doubts arise. They feel a deep relationship between them, because both are very sensitive, and understand each other at the level of their doubts and their fears. They share the same vision of the world and can form a relationship with great loyalty.
The doubts, the fears, the excessive emotions, and the anxieties so familiar to type 6 can thus arise in both at the same time without there being one that can reassure the other.
