Talk Is Cheap, Continued

humans are stupid

The math thing didn't work, so she redirected the discussion to evolution, where she posed the ponderable, "Why is it that only humans are blessed with superior minds, with the ability to plan and speculate?" (She must have practiced that question quite a bit, judging by the sudden jump in language level.)

I just realized the irony of the term "free talk" (which is when a high-level student elects to practice conversation in a lesson without the use of a textbook). Free talks, as well as any other talks that might happen in a lesson, are not free at all. In fact, they're pretty damn expensive.
