That's very interesting! Do you have any resources (books, videos, articles) that could give more information on that? I actually find that I now am almost completely fluent with my immediate family because even though a lot of them can be pretty annoying and manipulative, I don't let them affect me anymore. But when it comes to people, I still try to be as likeable as possible and always find myself holding back my true feelings. It seems like from what you're saying that we should be more expressive. That somehow, holding back is what results in our stutter?
