Robby Keene: I'm sorry I lied to you, Mr. LaRusso. I just wanted to get back at him.

Daniel LaRusso: I know. But you're never gonna find balance that way. You can't let that bad blood change who you are. I'm not saying you need to like the guy. I know I never will, but... he--he is your father. And believe me, you're lucky to have one. You just got to try to remember, he's--he's not a monster. He's just a guy with a lot of demons. Mr. Miyagi always told me there's no such thing as a bad student, only a bad teacher. And your dad had the worst teacher there ever was. It sent him down a wrong path. But you don't have to go down that path. Do you understand? You don't have to ever become... him. Trust me. You let go of all that anger, and I guarantee you, no matter what happens tonight, you go home feeling great.
