Thanks for this post. I'm trying to figure out whether I'm spectrum or not, and when I read something unusual like "Non-verbal: An inability to communicate with words, or a limitation to simplistic replies, such as one word yes/no. An aspie may be non verbal only when triggered (such as during a meltdown), non verbal nearly permanently (but retain the ability to type perfectly coherently) or selectively mute" I say wow, because I can be triggered into mutism or selective mutism. And how common is that?
