Do you answer questions that your teacher asks in class?
I'm sure that I may be in the minority that actually answers questions in class, but I just feel awful for the teacher that just has to stand in front of the class looking defeated as everyone gives them the blank stare of stupidity. I'm sure it's not very "cool" of me to still be answering questions, but I feel obligated when I know answer. It is one of my biggest pet peeves after four years of college.
Any others out there, or do we all go blank in class and sit on NS?
