Rose Mary Walls is upset when nurses give Jeanette chewing gum?

From the text:

"Ugh," she said. She disapproved of chewing gum, she went on. It was a disgusting low­class habit, and the nurse should have consulted her before encouraging me in such vulgar behavior. She said she was going to give that woman a piece of her mind, by golly. "After all," Mom said. "I am your mother, and I should have a say in how you're raised."
