Rounding Up

Driving home from swim team:

MADELEINE: Mommy?  When we get home, I'm gonna use my CRAFT supplies to make an imaginary CREATURE, and I'm gonna write "A.M" on it, because it stand for-
ME: Maybe you can make it in the morning, because it's seven already.
MADELEINE: It's six-fifty-eight!  (reprovingly) Mommy, that's a LIE.
ME: Honey.  It's not a lie.  It's called rounding.
MADELEINE: (indignantly) It's called "SIX-FIFTY-EIGHT."

Well.  She showed me.  She then proceded to stare at the car clock for the next two minutes so she could triumphantly announce, "NOW it's seven!"  Good thing she keeps me honest.
