"How dreadful!" cried Lord Henry. "I can stand brute force, but brute reason is quite unbearable. There is something unfair about its use. It is hitting below the intellect." ~ Oscar Wilde - The picture of Dorian Gray
About being verbal; I dunno about that. I find myself getting tongue tied and jumbling up my words constantly. Of course, that could just stem from the fact that I usually don't talk confidently unless I was truly comfortable around you. Kinda like what Quinlan said, actually.
For me, I get tongue-tied whenever I feel insecure or at times, when talking excitedly. People say that I have a very low voice..even when he/she is inches away from me..sounds like mumbling.
Maybe I wouldn't be so misunderstood if I wasn't always changing my mind...
And yes, I never feel like I express things correctly, or I get weird looks or pauses after I've said something and I take it as judgment, and then I think, 'No, I said that wrong. They don't get it. Why can't I say that in a way that they'll understand?" And I get flustered and I feel stupid and it kind of keeps me from talking in the future... for awhile, anyway. At least until I forget about it. And then it happens again.
