Symmetric relations.
Signs of corresponding functions are the same.
Function interaction: 1 ↔ 3, 2 ↔ 4, 7 ↔ 5, 8 ↔ 6.

In these relations one's ego interacts with the partners's superego and one's id interactis with the partner's superid similarly to the conflict relations. The function one  interacts with the parnter's function 3. Impression we get of our parnter can vary depending on his cultural level - we might be fascinated by the partner's "correctness", by the fact that he can easily be what we are painfully trying to make out of ourselves. But he also might remind us of ourselves in our youth when we didn't yet grow up to be independent. Superego is the block of most unpleasant feelings  - painful reactions of the function 4 and normative exigences of the society related to the function 3.

Superid doesn't get information of the desired quality: well verballized and explained, because id of each of the partners  produces poorly verballized individual, self-evident information. Constant demand of such information from the partner 's side might be annoying and cause discomforrt.
