I was thinking about how frustrating it would be to have an uncontrollable stutter, after I had a word at the tip of my tongue but that wouldn't quite making out in the midst of a presentation.
I searched for information about stuttering (stammering in British English) and found this documentary. It's very good. Great if you need a good cry.
I am grateful for being able to say my name without any trouble. (Seriously, that part just about killed me!)
