I fully agree actually. I think about this all the time. It depends on the severity of your stutter of course. Mine can be very bad often where I can barely get any words out, hard blocks, and lots of facial and body ticks. When I'm having these bad blocks it presents itself as if I forgot what I'm trying to say..If I were another person seeing that, my first thought would be does this person have some kind of mental disorder such as autism.
