Re: how many back talk would you take?
There's a limit to how much you can get into this stuff during class. You offered your idea, he countered, you're done.
But you could raise it again after class and the two of you could explore a bit. What happens if you strike a little harder? Is his block really ineffective? What happens if you do it your way? Can he really smash your face? Try it out. How else are you ever going to know?
