Well, as for the student asking dumb questions, well I honestly believe every school in the world has one. We had some nutter asking the world's dumbest questions for no other reason than to grab centre stage. As soon as she opened her mouth you could see/hear/feel the entire lecture hall cringing.
thats why i take online classes. i dont have to deal with those 16 and 17 year olds that are dual enrolled in both high school and college. they think they have it all figured out. a few times i had to stop this one guy and my professor thanked me for it. i told him to his face he needs to sit back, pay attention and listen to how it is and we dont want to hear how you think it is. damn sociology class.
