Is There a Third Category of People Who Don't Interact With Other People?

Some people might be just able to without a prepared context with an appropriate other partner, just picking a topic that was interested in and then start getting into it in a careful way. I would predict auto that acts will be terrible at that. One category is someone who just sits by themselves and thinks and comes up with things and just doesn't interact with other people very much at all. And then there could be a third group of people who might meet each other and are just do that  and then practice learn through practice to talk to each other usefullyWithout having been trained in that in some shared structured context. They would just reinvent their interaction.
