...you're getting ready for the Unified State Exam in mathematics, but then a bunch of friends show up at your place, drinking beer, shouting loudly, swearing, and breaking everything... (it happens to everyone, right?)
Out of anger, you kick them all out and study algebra until 2 a.m. After sleeping for only about 4 hours, you go to the math exam, but the kind teacher tells you that the exam was yesterday, and today is the literature exam!
I'm making some borscht!
