This is common for a few reasons: 1) People who stutter can become very skilled at switching out a similar word for a difficult word; but, you can’t change out your own name. 2) you don’t say your name often; typically people only use their name when they meet someone. For people who stutter, meeting someone is often an extremely anxiety- generating situation, and guess what? More often than not, when anxiety goes up, the stuttering does too. 3) Stuttering is considered a hidden disability; you can’t just look at someone and decide that they stutter. And because stuttering is so rare, people are surprised when they hear it. As you probably are aware, that look of surprise (or panic) when someone hears you stutter, almost instantly results in you stuttering MORE.
