Basically you stay up all night worrying about whether or not your gonna get into trouble e next day for not completing an assignment or homework for wherever reasons like let's say you werent in the previous lesson.

And then you get to elason and you find out either the teacher has set back the due date for the class giving you enough time to complete it (and you ask yourself what the hell was all that worrying about) or the teacher is not in and you have a substitute teacher and they dont ask about the homework or assignment that's due that day maybe because they didn't know or forgot and again you are relieved to have more time to complete the homework or assignment and wonder what all that stress and worry was about.
