Why do you feel that stutters are annoying to the people to listen to? Have people told you that or is it based on you feel when you listen to someone else stutter? In my experience only a small minority of generally impatient people can't tolerate listening to someone who stutters. I would rate his stuttering as moderate. He stutters on quite a few words, but it doesn't hold him back from communicating the message he's trying to say. My own stutter is far more severe than his. I stutter on as many words as he does, but then in the form of blocks instead of repetitions. Which makes me unable to finish my sentences on many occasions.
