Um. This probably doesn't help. But I'm often not terribly secure about my own intelligence, and while I feel fairly objectively certain I'm not stupid, I feel stupid a lot of the time.

For what it's worth, J. and I talk a lot more than you do. Which may be 1) intimidating and 2) giving the illusion of greater thinkiness than we would if we shut up once in awhile.

I'm not trying to speak for her, really, but to say that talking != thinking deeply, not all the time.
