You should mean it when you lie to me

[I was sneaking out of bed early one morning because I couldn't sleep.]

Laura: Why are you getting up?
Jack: You're awake?
Laura: Yeah, why are you getting up so early?
Jack: I couldn't sleep, thinking about stuff.
Laura: Thinking about me?
Jack: Um, yeah. You, and chess puzzles, and work. (Not necessarily in that order.)
Laura: You sure know how to woo your wife.
Jack: I'm going to sneak downstairs now.
Laura: To write me a love note?
Jack: Um, yeah ... love note.
Laura: You know, you're no longer my favorite person in the room.
Jack: Why not, I answered correctly, didn't I?
Laura: Yes, but you should mean it when you lie to me.
