After 6 hours together:
Stop wiping your armpit sweat on each other.
No, you can't bite your sister's butt. There are people in the car next to us.
Find something to do besides licking your sister.
Look out the window and count the trees.
I don't know how much further. We must be lost.
And I have learned that our kids don't get car sick on winding, curvy, hilly roads in southern Missouri. Thank goodness.
