Another example i remember vividly on the discord was hearing people stutter throughout but as soon as they said something else on the side, went fluent, then as they came back to us or the subject, the stutter took over.  Same with finishing.  All the way to the end of the sentence, then at the end it's like they felt a relief and said something fluently to finish knowing the subject had ended.   Of course I can relate and remember doing the same, still do probably, which is why when I hear how different stutterers are I wonder how someone like me with a totally different background, different sex, different everything, and I speak a different language, can understand what they are going through and relate entirely.   I remote thought that we might stutter on something can trigger the feelings which trigger the bodily reaction which bring it right up, that's why when asked to repeat something we just said fluently causes a stutter i believe, if not a block!  On something just said without a second thought.  When people go fluent at the end, I think the body let's go of the triggers knowing it's over.
