For me it's more of like, if I'm just talking randomly with a person I can usually get by without stuttering, but as soon as I have to answer a specific question, or if I get really focused on a topic, I stutter more. Like if you just asked me randomly: "What have you done this past week?" I would answer it normally, without stuttering, but if it's a specific question like: "What's your opinion on this political issue?", I'd stutter a lot more
