Position of the Week----Terror?

My yoga instructor is out this week. She is getting her "yoga butt" (yep), and her "yoga kids" certification. So, as she is telling us, and calling other students. I got nominated to step in for the instructor this week. So I left flattered and frightened. It should be interesting, because I have been looking in to a 200 hour certification. Can I talk and hold a pose? Those of you who know me, probably imagine I could talk even while dead. However talking while holding a strenuous yoga pose? An entirely different ball game.
