A Walking Contradiction

Betsy: You know what you remind me of?
Travis Bickle: What?
Betsy: That song by Kris Kristofferson.
Travis Bickle: Who's that?
Betsy: A songwriter. 'He's a prophet... he's a prophet and a pusher, partly truth, partly fiction. A walking contradiction.'
Travis Bickle: [uneasily] You sayin' that about me?
Betsy: Who else would I be talkin' about?
Travis Bickle: I'm no pusher. I never have pushed.
Betsy: No, no. Just the part about the contradictions. You are that.
