How about this. Rather than ooh this person is LSI so I am going to take their behavior at face value because socionics sez so, let's say socionics is right, and if this is actually someone's dual then they can fully call them on their behavior. Who else but your dual is going to deliver that message effectively?

Or maybe socionics just covers here for someone being crappy. Why is it that the possibility cannot be entertained that this is about childishness or narcissism or something ... Just because it's all so very beta?
