Teacher Kitano: Are my classes boring?
Noriko Nakagawa: Yes.
Teacher Kitano: How dare you!
Noriko Nakagawa: [chuckles]
Teacher Kitano: I go into class, you guys look like a pile of potatoes. Slapping them around helped me tell them apart, even got to like them. But now, not anymore. Now you touch a student, you're fired. Can't even lose it when a student stabs you!
Noriko Nakagawa: I'll tell you just one thing.
Teacher Kitano: What?
Noriko Nakagawa: That knife that stabbed you... actually I keep it in my desk at home. When I picked it up, I wasn't sure... but now, for some reason, I really treasure it. It's our secret, okay? Just between us.
Teacher Kitano: Listen, Nakagawa.
Noriko Nakagawa: Yes?
Teacher Kitano: What do you think a grown-up should say to a kid now?
