Who is Jo? How does she respond to her father’s story-telling?

Joanne is the eldest child of Jack and Clare. Her pet name is Jo. She is four years old now and has been listening to bed-time stories from her dad for the past two years.

Earlier when she was an infant, she’d fall asleep while listening to the stories. But now the entire scenario has changed. She doesn’t fall asleep anymore, rather she listens to the stories with interest and asks questions to her dad about the same. She has entered an interrogative phase in life and wants to know about everything in detail. She also remembers the sequence of the Roger stories in detail and corrects her dad whenever he says something wrong or different.
