Student

Person that's doomed to attend university for next 4-6 years, also has been doomed to experience pain, suffering, sadness, depression, laziness, helplessness, loneliness, tiredness all at the same time(list is not full). After person becomes a student, he starts to miss childhood. Facts about that species: they sleep 2-4 hours a day, their digestive system has adapted to energy drinks and junk food like cow is adapted to grass, it's their only meals.

But there's 2nd type of that species that has nothing in common, it's Student with girl- boyfriend.

- Congratulations, you become a student!
