Very cool, a stutter twin : ) Yeaahh I think so too... When I was in high school I had an oral exam and I had to give a talk about something and I practiced a lot at home but I couldn't say a word in class and the teacher was very pissed at me and I failed the exam. At the time I did not know that I am a stutterer, I just thought that there is something truly wrong with me and that I´m slowly becoming mute. I visited a speech specialist, who was able to assure me after some tests that I am a stutterer, but he also told me that the way I stutter was rather rare.
