What's interesting, I have a feeling that a person whom stutters but is still extroverted is actually deemed way more confident than a normal person. Normal people would probably think, if they stuttered they wouldn't be able to be as extroverted or so talkative. I've actually had people be envious of me that Ive attracted attractive girls because of my ability to joke around and talk to people regardless of my stutter. They don't have any speech problems, and they still can't even get a conversation going or they're lacking confidence. And then they see someone with a speech thing going on with more confidence than them. I mean these are not good people that think like this, but in the end they're more important things than speech.
