Several people actually. First person was a girl in college, then several people telling me they use to stutter as kids. The latest person was a coworker. He had such good fluency and technique that I didn’t catch on until a month after meeting him. Everyone at different levels, techniques to work through it. The most interesting ones were a group stuttering session in college. The therapist stuttered herself but had significant control on fluency. It was incredible to watch. Others in the group were very severe. As someone else said, somehow when talking about my stutter, my fluency really improves. I occasionally vent my frustrations with friends and my wife and they totally get it without stuttering themselves.
