The resort town of Aachen in Germany is once again illuminated by the sun. You are going to university to study mechanical engineering. You enter the classroom. The students sit in the classroom at the front desks. You see your friend Strade in the last row.

Strade listened to music and drank beer, which he poured into a juice can so that the teachers would not find out. You sat down next to him and he took off his headphones.
