If u live with someone honestly not doable if your doing it on purpose. It would just frustrate the other person, whether or not theyre also autistic. This is simply because conflicts or important questions come up.

If your not, just consider staying home for a whole weekend or more. It is nice to have rests like this for me.

But I would seriously consider why you want to be non verbal. Its not likely to be healthy at all. I think, and im sure other people feel the same, succumbing to my desire to hide from the world would be so catastrophically unhealthy. I know this because thats what I did. I in effect was non verbal for months on end, save for my best friend in the world and cashiers I suppose. It very nearly killed me.
