It never fails.
The first few days (or week, or two) of a new module are always dedicated to catching up on all sorts of life things that I didn't have time to take care of during the last few weeks of the previous module and didn't have the energy or motivation to take care of during the weekend following the exam. Those days are needed for relaxing.
Things like laundry. And laundry only feels relaxing when I am doing it to procrastinate on something even less relaxing.
