Leave it to Addie to be good at science... When the family was driving across the continental divide, I was trying to see if Ellie knew where the water goes, thinking that on one side of the divide it goes to the Mississippi River and on the other side it goes to the ocean.
Mommy: Ellie, if we're at the continental divide, can you guess where the water goes from here?
Addie: (interrupting any chance for Ellie to answer) DOWN!!!
Can't argue there.
