not sure why I feel the urge to reply :) but Zack is the very opposite of that teacher. Zack is asking questions and wants to learn. That teacher just tries to push her opinion on someone, leaving to room for reply, no room for a conversation, exactly what no teacher should do, no one in general but especially someone who should promote discussions, questioning and argumentation

In this context I can easily imagine that Zack is the teacher.
