"Mommy's a Princess!"

Recounting a conversation from earlier today....
Lily: "Mommy's a princess."
Mommy: "Awww, that's so sweet of you."
L: "Lily's a princess."
M: "Well, yes...."
L: "Daddy's a princess."
M: "No, Daddy's a boy. Princesses are girls. Daddy can be a prince, but not a princess."
L: "I'm a boy."
M: "No Lily, you're a girl."
L: "Mommy's a boy."
M: "No Lily, Mommy's a girl."
L: "Daddy's a boy."
M: "Yes, Daddy's a boy."
L: (after a little bit of thought) "Daddy's a boy, Mommy's a girl, and I'm a princess!"
