I stutter when I get nervous and then I get nervous when I stutter. Or sometimes I don't say my words loud enough and then someone asks me to repeat what I've just said and I try to repeat it without breathing in first so that I'm trying to talk at the end of a breath. But that creates more of a stammer than a stutter. But I don't really differentiate between stutter stammer. They both suck and they both cause the same end result which is someone looking at you like you have six heads. I've heard though that when people sing, they don't stutter. I don't know if anyone's seen that Tony Robinson video where a black dude was a terrible stutterer and Tony suggested that he kind of act when he talks. So he sort of started to talk loud and put on a show and he never really stuttered afterwards. I kind of thought it was more of an act than an actual real issue with somebody, but maybe it wasn't.
