Runaway, your...dang...still at a loss for words. Kudos, nail on the head.
Introverted would also loosly explain the DnD subculture: People who gather and play out a game, all in their head, thinking five to six steps ahead of eachother, finding loopholes, and in the end, arguing with themselves wether so-and-so shouldn't have done such-and-such. (yeah, DnD geek here)
I'd say, I'm a Introvert to the true deffinition. Often overthinking subjects, trying to read too hard into what others are saying/doing, mumbling to myself, and finding the PERFECT whitty retort...five hours after it should have been said.. All in all...I'll probably edit this post with a few of my thoughts....later....when I have mulled them over.
