Reverend Theo: I knew you were old. . . I'd forgotten exactly how old, though.
Vog: Twelve million of your years, give or take a little bit.
Reverend Theo: "A little bit?" How much is that?
Vog: I don't know. Just because I'm old doesn't mean I'm good at math.
Vog: Conversion between my time scale and your own standard Earth years isn't hard, but there are a lot of zeroes. rounding may introduce as much as a one percent margin of error.
Reverend Theo: The margin of error in your guess at your own age is bigger than the age of my whole species.
Vog: Like I said, I am having trouble understanding your perspective.
