I have realized that when I speak simultaneously with someone else, like we coordinate what we want to say and 3 2 1 say it together, I don't stutter and even there is no anticipation or feeling of stuttering. I have also had the other person randomly stop saying the word that we are going to say at the same time, and I still don't stutter as long as I THINK that person is going to say it with me. I think it has something to do with the idea of communication. For communication you need 2 sides. My side and the other side. And I think my side somehow gets mixed with the other side and that's why I stutter and saying a word simultaneously, somehow fixes that. This is my crackpot theory 🤣
