My professor wasn’t expecting that! Proof of achievement in the stairwell!
Luckily, I can always sleep in a little on Fridays because my lectures start later. When I was about to go into the university, my professor, whose module I was studying afterwards, spoke to me. Apparently he found out what I was doing on the side AND he also said that my performance had dropped. What should I do now? On the other hand, I've noticed recently that he's always looking at me like that. So I thought to myself, no risk, no fun! He already knows anyway! Maybe he prefers a different kind of proof of performance from me. I then led him into the stairwell and showed him what I've learned recently.
