Kindred relations are characterized by the high level of understanding between partners and at the same time by the mutual discomfort of each others behaviour. That is because they both have the same aspect in their “Leading„ function, yet their “Creative„ function clashes with their partner's “Vulnerable„ function.
This kind of relations are good for seeing the ideas from a different angle. It can be very valuable to share ideas with a Kindred partner as long as one is prepared not to take criticism personally and remember that the other partner has different life attitudes.
But in a long run, if relations are close, they are hard on both partners and both normally need time to relax on a distance from each other.
