Mitchell: Hey, Lily! Come here, honey! Hi! Do you know what this is?
Lily: A box.
Mitchell: Containing?
Cameron: She doesn't know "containing."
Mitchell: Well, that's how she learns new words, by us using them.
Cameron: Or, that's how we lower her self-esteem, by bombarding her with confusing vocabulary.
Lily: What's the box containing?
Mitchell: Told you.
