TheDad is helping Middle Sister prepare for a math quiz. She was absent from school for a few days, and her teacher recommended that Middle Sister review a few lessons. Middle Sister resisted the review, but TheDad said that they were going to keep at it until she mastered the concepts.
Finally, she seemed to get the hang of it. "Very good, Middle Sister! I'm so proud of you," TheDad said.
"If you were proud enough, we'd be done," she responded.
