Surprisingly idk why but when I do a presentation I stutter very little if at all. I think it’s because I kinda disassociate a lil bit or something like I’m watching someone do a presentation and it’s a perfect presentation lol. That was in hs and thru university no one really cares anyway. I’m 27 now and I still have a bad stutter even at work but if I have to show someone new something I imagine it as a “presentation” and it goes better.
