Idk. I do know that before doing any work on stuff I have had the tendency to come across vague because I felt uncomfortable divulging any personal details about what I was actually doing with most things. Privacy to a pathological extent. Some people reacted by trying to suggest my speech was "vague and impressionistic" and therefore thought I was histrionic, when actually I was extremely unhappy about having to tell people anything. It did make me seem vague though because I had to appear to respond without actually giving an answer. lol
If I stop talking its often because of cognitive dissonance and anger I can't process through the conversation without being hostile, even if e.g. in relation to how I'm responding, i.e. attempting and then just refusing on some level half way through. edit: actually that hardly ever happens, its only tended to happen because I was dissociating at the time.
