I Subbed a English class. (High School ) The Teacher left on the Sub note saying * Students can't go anywhere, Restroom, Nurse etc etc Unless it is a true emergency. So during the passing period a student asked * Can I go to the restroom ? I asked * Is it a emergency ? The student looked at me confused and went in the classroom and sat down. I was thinking * Ok, that was weird. During the day other students asked for the restroom and I would ask the question , is it a emergency ? They all said * Yes ! Until...... Another student asked * Can I go to the restroom ? And I ask * Is it a emergency ? He looked at me confused and went and sat down. He did that at least 5 to 7 times. I don't think those two students could understand the word emergency and that was English class. P.S. I was not going to go to a lot of trouble to correct the understanding of the students on that issue as the Teacher made it clear that students leaving the class was not to happen. Unless of course it was a emergency.
