Baby Sister

One of Tessa's favorite shows is the Bernstine Bears. No one in the Bernstine family has names, they're just called, Mama, Papa, Brother and Sister.

"Tessa, what is your baby sister's name?"

"Sister."

"Yes, she's your sister. What's her name?"

Tessa shrugs.

Someone else asks, "What's the baby's name?"

Tessa thinks for a moment. "Kenny!"
