I read on a great book called Re-defining Stuttering by John C Harrison that stuttering is all about holding back our emotions. That is why we block. We are blocking something. That something is our own emotions. We, as PWS, have a hard time expressing ourself and releasing emotional content to other people So we hold back. Personally, I think we can´t handle the posible reaction of the other people to our own emotions. You see, emotions are so easy to trigger other people feelings. When someone is sad, you get sad. When someone is angry, you get angry, And so on. Well that is just my take. Farewell.
