This passage between Caddy and Rose after Tom has left:
It had not seemed to matter that Rose was only eight years old.
"More than eight," said Rose. "Nearly nine."
"Darling Rose, even almost nearly nine-year-old's don't fall in love," said forgetful Caddy.
Caddy tried very hard to comfort Rose when Tom had left. It was not an easy job. It was like trying to comfort a small, unhappy tiger.
"Who said anything about falling in love?" growled Rose crossly. "Falling! Falling is by accident! I didn't fall in anything!"
"Oh. Right. Sorry, Posy Rose."
"And I am definitely not in love!"
d-awww. Rose is oblivious to her crush, which makes her furious denial over it so heartwarming.
