You can't think of anything to do so you start spinning in your chair. As this continues, you weren't aren't aware that your elbow was getting closer and closer to your open drink on your desk, until BAM!
You knock over the drink onto your textbook and laptop ruining both of them. You are unable to access any of your school work online and all of your physical papers are ruined.
You end up failing your test since you were unable to study for it.
Better luck next time!
