KB:"What are you doing, Mommy?"
Mommy:"I'm doing my homework?"
KB: "What kind of homework?"
Mommy: "Organic Chemistry homework. I'm learning about protein."
KB(climbing up on couch next to Mommy): "Oh, protein."
Mommy: "Did you know that there is protein in lots of the food we eat, and then our bodies use the protein for lots of things? Like building things in your body? There is protein in your skin, and in your muscles, and your hair, and your fingernails..."
KB (rolls onto her front, and peers back down over her shoulder): "Is there protein in my butt?"
