Where Does the Pilot Sit Again!?

Chad's mom just bought some new lift-the-flap books, which Elianna just loves. In one book, there is a picture of an airplane. When you lift the flap, you can see the cockpit. Grandma read it to her, and said, "See this is the cockpit, where the pilot sits." Elianna looked confused at this, and said, "This pit?" And lifted her arms. Grandma explained, "No, it's called a cockpit, not an armpit." We assumed she understood, but a couple days later she asked for Grandma to read to her. Grandma asked, "Which book do you want to look at?" and Elianna yells, "Armpit!"
