(You're from the Slytherin house)

today you had a joint lesson with other faculties, namely Gryffindor. sitting down on the desk, next to you you saw a guy who was apparently asleep. you decided not to pay attention to him and focused on the lesson.

after a couple of minutes, someone poked you with a finger on the shoulder, turning in his direction, you saw that your neighbor at the desk woke up.

— what topic are we studying?

he asked with a straight face, waiting for your answer.
