In posts, most of you seem to be clear and intelligent. Are you like this when you speak in real life as well?
In real life, I am rarely clear when I speak. I stop, backtrack, and am always saying, "Oh, that reminds me..." and spinning off to another point, while people give me confused stares. This is when my mind is really going.
Other times I freeze up and can only think in the simplest of terms. At these times - when I am very nervous - my brain refuses to grasp abstract concepts, and I can't think of a single intelligent word to add to a sentence.
Only when I talk about a special interest with people I trust does my IQ seem to skyrocket, and I magically become articulate. In posts, I feel I am not always as clear as I could be, but at least I have time to think of what I want to say. And yet still I ramble...

I think what you described is the main thing that makes an aspie, that is exactly how I am.
