I think you'll find that most, if not all, human conversations are embedded in a context, which carries assumptions, so that participants can understand each other without iterating all of their definitions. That's why, for example, I don't have to start every conversation in my life by clarifying that I will not be explaining everything in terms of Xenu and thetans. And if I did want to explain things in those terms, I should first explain why that's a valuable frame to adopt.
