I'll Bet Mommy's More Interesting Than the Letter 'R'

Fiona, waking up earlier than usual this morning (but still at a reasonable hour), calls out for Daddy to open her door. Daddy turns on the coffee and obliges.

Fiona: (after Daddy opens the door) Good morning, Daddy!
Daddy: (leaning down to give his daughter a hug) Good morning, Fiona. Did you sleep well?
Fiona: Yes.
Mommy: (sitting up in bed) Good morning, Fiona.
Fiona: Mommy.
Mommy: Do you want to give Mommy a hug?
Fiona: (seeing the refrigerator letters and running into the kitchen) Oh, a letter 'S'!
