Check out the newest episode of my course, "Master Politeness Levels." In this lesson you'll get an overview of politeness levels, and learn why they're so important.
Every week I'll upload a new episode of this course. There will be a total of 24 episodes once it's completed.
If you're a Member of my YouTube channel you can (as of today) watch up to Lesson 11 of this course too, with more on the way soon.
