How does saying "did you forget your name?" anything other than making the way you've said (or paused) into a "joke" that intends to tease? I don't mean to come off hostile, but I'm genuinely confused. That phrase is "intended" as a joke at the speaker's expense. It might not be mean spirited, but it is meant to be a ribbing. Most other stutterers I meet personally are very forgiving and assume people don't mean to hurt them. Usually this means we never stand up for themselves, or tell the other person that it hurt. Which results in people hurting us and others without realizing. I'd be horrified if I realized I was hurting someone, and I'd want them to tell me so I could change.
