try to read about "schiziod" personality. It is basically the extreme version of a loner. People that are happy with themselves, don't like contact with other people, and like to keep the human relationships in minimum as possible. Seems ok in surface (and many schiziod people are happy withe themselves), but in few people it is a precursor of schizophrenia. http://en.wikipedia.org/wiki/Schizoid_personality_disorder http://en.wikipedia.org/wiki/Schizoid_personality_disorder
