I stutter and use "um" and "like" a lot.

A lot of people think that stuttering and those "um/er/uh" pauses in speech mean the person speaking is unintelligent, and I've always been sort of afraid of them thinking that of me. Even though I could probably whip up a fairly eloquent speech on any number of subjects, if I have to actually speak I sound like I have a vocabulary equal to that of a third-grader. So I don't talk.
