I had to cover an instructor who called in sick. I never had her students before. When I walked into the class a student dropped her jaw. Just with their body language this large class communicated to me that I was not welcomed. Before they could pick up their jaws from the floor I immediately introduced my self. I gave a brief explanation about what happened to their teacher. I told them not to worry that they were in good hands. Please share any suggestions you might have for instructors who might come in the middle of the quarter to be the new permanent teacher. I also like to get some input for the teacher who has to cover a class for a day with very little short notice. John
