How we cite our quotes: (Part.Chapter.Paragraph)
Quote #4
"How about your parents?" Stewart asked. He was resting his head against the back of the chair, looking at her.
It wasn't that she couldn't lie to him. She could lie to anyone and make it good, if she had to—she'd certainly discovered that. But she didn't want to, not to him or to Windy. She wasn't going to lie to them, she decided. (1.7.136-137)
Here we see Dicey finally deciding to trust someone, and opening up a bit. Before, she had to be leery of outsiders, but she believes Windy will understand and not try to do anything to harm the kids. That's why she finally tells the truth.
Quote #5
"I thought Aunt Cilla was rich," James said. "This isn't a rich person's house."
"I must have been wrong about that," Dicey said.
"Momma said she was," James insisted.
"Then Momma was wrong."
"Do you think Momma's here?" Sammy asked. "If she's here why isn't she here?"
"I dunno," Dicey said. "It's Thursday, a working day, isn't it? So if she's got a job she'd be there, wouldn't she?"
"What about Aunt Cilla? Is she too old to work?" James asked.
"I don't know anything about her except what she wrote in her letters—and that wasn't true."
"Why would she lie?" James asked.
"I dunno," Dicey said. (1.9.5-14)
Why would Aunt Cilla lie? Dicey lies to protect her family, but it seems Aunt Cilla lied to make herself seem rich and important. Her lies cost the family, because Momma set out on this whole trip because she thought she might get help from Aunt Cilla.
Quote #6
Dicey found herself ready to lie again. She could say they were visiting and the children had come to meet Aunt Cilla, and then later the Tillermans could go off and—and do what? If she lied, then she would get herself into a box. They had come such a long way. They had to have some kind of help from this cousin she'd never even heard of before. (That was strange too, that Aunt Cilla had never mentioned a daughter.) If Cousin Eunice didn't help them, they would have to go to the police. Dicey had to tell the truth. (1.9.74)
Again, Dicey has to tell the truth. She's probably right to suspect that she can't completely trust Cousin Eunice to help them. But she's also smart enough to know that she can't fib her way through this situation if they're going to live here.
