I feel that the theme in these lines has something to do with law, ruling, listening, obeying and being in charge.
A few quote examples to help support this theme is/are: "...girls usually side with their mother...."
"...her authority in the home shrank as my mother's authority gradually extended..."
"... the law of life..."
"...obey the law readily and willingly."
What do you mean? do you have multiple choice answers?
Good Morning have a nice day Ahead
