I've been told I'm very verbose and eloquent in my writing style. However, when I speak, I often get nervous and stumble on words, and would seem to other people very far from verbose. If I've gotten to know someone well, I will be somewhat more eloquent and verbose when I socialize with them, but if it's with people I don't know well, I will stumble, pause, and my mind will often go blank trying to think of the right words. I guess I just have a somewhat bad case of social phobia. When I'm relaxed with someone, I can be slighty more verbose, but not by much.
My therapist, however, seems to think I'm quite eloquent when I speak about a subject I'm interested in. Maybe she's right to an extent. But I just often get too nervous when I'm speaking with people, so my eloquence doesn't come across very well. I'm often tongue tied in social situations, although if a subject comes up that I'm interested in, it won't be as bad. I'm just not very representative of the stereotypical "little professor" of Aspies, because I get nervous.
