Getting together and dissecting exam performance just after it’s all done with is a rite of passage for all college students everywhere. You run through the questions, either despairing that you got totally the wrong idea on question 2, or discovering that you probably answered the second section a lot better than your classmate.
It’s a totally different story if you’re this guy, though. Imagine texting your friend to ask how he thought he did on the exam, only to find out that he’s completely missed it, and you were the one who broke the news. Diego seems to have had some sort of stroke at the realization, I hope he’s ok.
