Lily is young, eight years old. She doesn't understand the purpose of some rules, and simply doesn't want to obey others. Early in the book, she expresses the anger she felt when a visiting child at her school didn't obey the rules about taking turns and is reluctant to accept her parents' reasonings to explain the behavior and that her reaction was not justified.
Lily is pleased to be old enough to be able to dispense with hair ribbons, required for seven-year-olds, and looks forward to receiving a bicycle of her own. She is not looking forward to giving up her comfort object but realizes this time is coming.
Lily doesn't seriously question the structure imposed by the rules in the community. She challenges those that directly impact her self-centered view of life, but accepts the order and organization created by the rules as being the best way of life.
