The differences aren't invented. I see them every day within my own family. My Dad literally argues with himself out loud. I used to think he was arguing with me, but he's not, because now I just remain silent and the argument still happens. He's not being brash, and he's not shooting first. He's just figuring out the problem with his own method. And when he's done, he's usually right (warning: son idolising father bias).

I don't see the problem labeling my Dad an extrovert... there's nothing negative about it, and it describes one general aspect of his personality pretty well. Even more so, recognising this aspect of his personality has helped me interact with him in a much more productive manner.
