I have a theory that maximum intimacy between two people requires both people to have the same "approach" to problem-solving. e.g., in the Meyers Briggs model, some people are conceptual thinkers, some are conceptual feelers, some are concrete thinkers, others are concrete feelers. I have no idea if the meyers briggs model is right.. but my theory is a mismatched pair can only hope to obtain what I'll call a "mutual respect / acceptance level of intimacy", which is a far cry from the full intimacy that a matched pair can obtain. Not a psychologist... just a guy with a theory. Now go beat it up!
