I am a different type of weird then. Sometimes I know exactly when I'll stutter, I'll even speed up to get everything out before the tension creates a block. Then, sometimes I just stutter and its a surprise... sometimes I even say WTF out loud after a weird stutter. And sometimes, I think I am definitely NOT going to stutter then I do. Its random until its not. However, I have noticed that if I think I will stutter, then I do. Always.
