Stutter less when nervous

Stutter less when nervous I know this makes absolutely zero sense but I stutter less when nervous like when Im with a friend im super comfortable with and I dont even have to think about what I have to say just blurting random stuff without a care in the world I stutter. However when Im with people im not comfortable around or meet for the first time I do not stutter as much despite being extremely nervous. Shouldnt this be the exact opposite though?
