Question

Why was the story telling session especially tiring for Jack on Saturdays?

Answer 1

Jo barely felt sleepy since she was growing up and becoming curious. She would often interrupt the story Jack is telling since she had questions and clarifications to ask. She is not the previous girl to accept blindly whatever her father told her. Jo is thus very active instead sleepy during these story sessions

Answer 2

Answer:

Storytelling had become a necessary practice for Jack in the evenings and on Saturdays. It was for his daughter Jo so that she could have a nap. This had been in practice when Jo was two years old.

Explanation:

Storytelling to Jo had become quite fatiguing for Jack because Jo never fell asleep in naps anymore; she had grown young and didn't fall asleep. Earlier when she was two or three years old, she would fall asleep listening to the story.

Jack is especially tired of the story time ritual because he has run out of ideas for stories and Jo never falls asleep in naps anymore. Indeed, Jo is growing taller by the day and Jack notes that her legs now stretch halfway down his bed as she snuggles in for her story.
