We’re in the car with Opa and Oma, making the trip to the mountain house.
B — R, don’t frown on this trip. You’ll use up all your energy. I read in that book about the human body that you use 37 muscles to frown, but only 17 to smile.
R — I read that, too! Let me see you frown.
B does as he is asked.
R — Wow! You do use a lot of muscles! Look how your forehead gets all wrinkled.
B– And you can see all my guns when I show my teeth.
