These are relationships of mutual correction. Mirror partners have similar interests and ideas, but a slightly different understanding of the same problems. Each partner can see only half of one problem. Therefore the partners always find what the other partner is thinking interesting. Usually partners quickly realise that they are very like-minded.
The area of confidence of one partner is always the area of creativity for the other partner. What one partner considers solid and final appears incomplete and changeable for the other partner. This difference may often puzzle the partners especially when they fulfil their mutual plans. It seems for them as if the other partner simply misunderstood the main concept. Therefore partners attempt to correct each other's understanding but usually fail, because each partner acts from their confident side. For the same reason, Mirror partners can be involved in really hot disputes and can even come to blows in the name of their opinion.
However, Mirror partners are often very good friends. When they work together on the same project, their mutual correction and adjustment becomes a constructive criticism that is usually accepted as useful. The main discomfort in these relationships is caused by the difference in Judgement and Perception between the partners. Mirror partners generally agree about setting near future goals, but disagree about global aims. Mirror relationships usually lack warm atmosphere between partners. This situation normally changes in presence of a third person who is Dual to one partner and an Activity partner to the other.
