A Conversation During World War Z

Craig: She's gonna turn.
Me: No, no she's not.
Craig: Oh yeah she is. This is the plane from the trailer where everyone's flying out turning to zombies. It's gonna be her. Oh sorry. Spoiler alert.
Me: No, it's cool I like to be informed.
Craig: Good.
(pause)
Me: It's gonna be that dog. I bet you it's that dog.
Craig: Oh for sure! (cackles) The dog's infected!
(pause)
Me: Oh wait, it's not the dog. There's a zombie in that food thing.
Craig: Dumb-waiter zombie. God, they're good hiders.
(later)
Craig: (cackles) You thought it was the dog!
Me: Why else put the dog in there!
Craig: Oh, for sure, you totally had me convinced.
