VERONICA MARS: I'm Veronica, by the way.
MAC: Mac.
VERONICA MARS: Is that 'cause you're good with computers?
MAC: Ah, no, 'cause my last name's MacKenzie. How did you know I was good at computers?
ME: "I watched the last episode of Veronica Mars last night, I wish there was more!"
YOU: "I know. Which is your fave character?"
ME: "Veronica, obviously, and Logan cos I love his quips, but Mac is my most favorite."
