for me

i gave 2 classes a comprehension assignment last week;
1 class just accepted the paper with nary a squeak, and proceeded to complete their assignment

the other class, objected and suggested doing something else...???????

then there was a hug commotion because I had made a mistake in the printing of the compre paper;

I shushed the class and told them...
you know, my colleague told his class that he is not going to mark this paper, and they should do it just for practice, and the whole class quietly did it; Here i say i will mark your paper and you make so much noise!!!

REtort from student: at least their paper was printed in the correct order...!!!
