I liked this. Always good to try to make students understand how to act, behave and be respectful in class so they learn better.
I put it here in the general section instead of "video section" hoping to get a discussion and hear more about your own approach as teachers and/or students.
My own and only objection is about asking questions. Sometimes it's good to ask questions if you know how to ask the right questions.
