At the beginning of a semester, I will tell my students that the most important lesson they can learn is RESPECT. I expect my students to respect me even as I respect them and I expect them to respect each other. There can be no deviation from this. No matter how intelligent you think you are, or good looking, or hip, or cool or entitled, there is no excuse for being disrespectful to a fellow human being. Sure, I can appreciate that people go through different situations in their lives and at times, they make mistakes and lash out in ignorance but that is no justification for disrespect. Period.
