One of my favorite scenes from the original Karate Kid

Daniel: Hey - you ever get into fights when you were a kid?
Miyagi: Huh - plenty.
Daniel: Yeah, but it wasn't like the problem I have, right?
Miyagi: Why? Fighting fighting. Same same.
Daniel: Yeah, but you knew karate.
Miyagi: Someone always know more.
Daniel: You mean there were times when you were scared to fight?
Miyagi: Always scare. Miyagi hate fighting.
Daniel: Yeah, but you like karate.
Miyagi: So?
Daniel: So, karate's fighting. You train to fight.
Miyagi: That what you think?
Daniel: [pondering] No.
Miyagi: Then why train?
Daniel: [thinks] So I won't have to fight.
Miyagi: [laughs] Miyagi have hope for you.
