For some people relations are a holiday, for some people it’s a business-trip (though into an armed conflict area sometimes), for others it’s sweet home. These concepts of relations as of some life “norm” or some “deviation” from its main stream are not consciously recognized and for this reason they have absolute power over a human defining his (or her) usual “alone” or “together” state making repeat it again and again.
Direct and violent people are unpredictable short-term, soft and compliant people are unpredictable long-term. You’ll never guess what stunt call one pull in a minute. You’ll never guess what trick another one can pull in ten years of marriage.
