We seldom understand where the other is coming from, personality types are only one piece of the puzzle.  Personality, learning/thinking style, and specific situations among other things always affect how we interact with each other at any given point in time.  I  greatly dislike the question, “What are you thinking?”  But I was never sure why, until this quote explained it for me:

Introverts rarely say what they are thinking.
They say only what they have thought.

Introverts think to talk.
Extroverts talk to think.

In order to answer the question, “What are you thinking?” I am forced to rethink it in a different way, for a different reason than I was thinking about it before.  I’ve already thought about it and now I’m thinking about why you’re asking me what I’m thinking.  And I rarely say something I haven’t thought through in advance.
