Semi-dual relationships

These are relations of incomplete duality.
Partners has good understanding of each other in words. They come to common subjects during conversation. Problems appear when they begin to put their plans into action. The extrovert often does not listen to the introvert. But the introvert does not take offence at such behaviour of the partner.
Semi-duals always have enough topics for conversations, and these talkings do not tire them.
Semi-duals with the opposite gender can feel attraction to each other. The problem is that their behavioral functions are not supplemental, and it is common for such relationships when one partner does something unacceptable by another one. As a result attraction can be destroyed quickly.
But, partners do not take offense at each other. They calm down, and try to find something common in partner, to stumble on a "flat place" once again. Such relationships are full of real passion and love.
Semi-dual relationships keep partners in a good health. Partners do not give each other to relax, and it helps them to be in a good fit. It can be compared with washing in cold water after incomplete awakening in the morning. Partners can be happy to see each other, and then come to bewilderment and disappointment.
