Do you stutter speaking alone? And how to talk to other people like when we are alone? Is there a way to "switch" from one to another?

Do you stutter speaking alone? And how to talk to other people like when we are alone? Is there a way to "switch" from one to another? Hi, how are you all? so I decided to ask you common questions I have.. I was wondering, every time I speak (whether alone or with family), I NEVER stutter.. . but I do with everyone else. I can talk A LOT, practically without stuttering. Is this normal? Stuttering is very mysterious. Kinda like it has a mind of it's own. Maybe there are subconscious cues? Does anyone else psych themselves out?
