It is hard to complete the class when the instructor makes fun of the students. Making faces, pouting and whining like a small child as he is making fun of the students. Then has the nerve to state in the next lecture you must respect your audience. I think what I will get out of this class is how not to treat others. Maybe this is how you get students to remember what you were talking about. I don't remember what point you were trying to get a cross however, you are correct, I believe I will always remember how you treated your students so badly.
