When introverts are in conflict with each other...it may require a map in order to follow all the silences, nonverbal cues and passive-aggressive behaviors! Adam McHugh Oh boy.  As an introvert and as one who observes behaviors of others I can say that this statement is pretty spot on.  Disagree with me all you want but stop for a moment and observe below the surface and you'll end up agreeing with me and therefore with McHugh.   I think the reason a lot of introverts passive-aggressively argue with others is  because  of that introverted nature that keeps them from even engaging in arguments in social ways!  Also, a lot of introverts that I know are peacekeepers (different than peacemakers btw) and peacekeepers are generally people pleasers (also better known as having fear of man) and people pleasers approach conflict in passive- aggressive  and nonverbal ways.  I know, I am one!  And I've had to work really hard, and still have to work...
