After daylight savings time, check, double-check, and triple-check that your alarm is not only set but also working correctly before Monday morning. Inevitably, it will look correct but will go off AN HOUR LATE for absolutely no reason. Inevitably, this will happen on the day your professor is observing your class for the first and only time. Inevitably, you will be too flustered to remember to bring all the materials for your class activity to class. Inevitably, you will have to leave the classroom and literally run back to your office in heels, leaving your class to your professor. Inevitably, you will be embarrassed AND end up with pit stains.
Luckily, you brushed your teeth. That’s about it.
