In the movie Collateral Beauty, in the following dialogue between Claire and Raffi, I can't understand why Claire calls Raffi "nine":
Claire: "That was the worst thing I've ever done."
Raffi: "That was the best thing I've ever done."
Claire: "What was that thing you said about Einstein in there?"
Raffi: "Einstein called time a stubbornly persistent illusion."
Claire: "What's that even mean?"
Raffi: "Time doesn't go from January to December, or from noon to midnight. You know, we all just make it that way in our heads."
Claire: "That's absurd. Try telling that to a person who's an hour late to a wedding or was just sentenced to 20 years in jail."
Raffi: "Or someone fighting a baby clock."
Claire: "We really don't need to have this conversation, ever. Anyway, just... Yeah, wanted to say great job today."
Raffi: "Just a stubborn illusion, Claire. You have all the time in the world."
Claire: "You're nine!"
Raffi: "You're nine."
Raffi isn't a 9 year old boy, so it's not about his age, I guess. What does it mean then?
