It's so annoying when people say "people who stutter don't stutter when___" I've heard people say: "People who stutter don't stutter when they read out loud" "People who stutter don't stutter when they curse" "People who stutter don't stutter when they talk to themselves" This may be the case for a lot of people, but some people do stutter when they talk to themselves/read out loud/curse. I stutter on curse words just the same as any other word. I don't usually stutter when I read out loud or talk to myself but I definitely have before, as I know some other people do. Please let's stop acting like everyone has the same experience with stuttering.
