Final answer:
In Shakespeare's play Romeo and Juliet, Juliet breaks the marriage customs and goes against societal expectations as a child and daughter by defying her parents' wishes and secretly marrying Romeo.
Step-by-step explanation:
In Shakespeare's play Romeo and Juliet, Juliet breaks marriage customs and goes against what is expected of her as a child and daughter in several ways.
Firstly, Juliet defies her parents' wishes for her to marry Paris, a man chosen by them for her. Instead, she falls in love with Romeo, a member of a rival family. This goes against the societal expectation for her to follow her parents' decisions in matters of marriage.
Furthermore, Juliet secretly marries Romeo without her parents' knowledge or consent, showing her agency and independence in making her own choices about whom to marry. This action is in direct contrast to the arranged marriages that were customary during that time period.
