The first part of your personality type is whether you prefer extroversion or introversion (this is important it determines the order of your cognitive functions for example Ti- Ne in the INTP or Ne-Ti in the ENTP) to determine whether you are introverted or extroverted decide where you get your energy internelly or externelly this might be difficult, there are introverts that appear to be extroverts or there maybe extroverts that are more reserved ( i am an example of this i actually thought i was introverted for some time). Now being extroverted doesn't mean you enjoy large groups of people it only means you are energized by your enviornment whereas an introvert would enjoy being alone which would cause them to appear distant or cold. A partership between these types would be a classic Calvin and Hobbes story where one would view the other as to impulsive not thinking things through, too loud, and obnoxious at times where on the other hand the other would accuse the other of over thinking things, being distant, and absent minded. Now remeber these are only stereotypes they don't apply to everyone. I hope this helps!
