He is like his father. Stefano also was bored in school. Although very intelligent with a finely tuned "common sense", it seems that Stefano left Bocconi studies before graduating as he was too eager to begin his career. It looks like Pierre also feels he's just wasting time and going through the motions. I think he wants to just get out there and live, not "delay" the inevitable with some boring textbooks and exams. He is clearly not a bookish guy, so he shouldn't just go to college for the sake of going. I bet his father would advise him to leave the university and start doing what he really wants. Better to leave his seat open to someone who really wants it, ya know?
