Question

Why does Janette choose not to get married?

Accepted Answer

I don’t know which Janette you mean — could you tell me the book, story, play, or film (and the author) so I can give a specific answer?

Explanation

If you meant a particular character named Janette, different authors give different motives. Here are common, text-based reasons a character might refuse marriage and how to find evidence in the text:

Desire for independence or self‑fulfillment — look for passages where she rejects conventional roles, expresses wanting a career, travel, or personal freedom.
Lack of love or incompatible partner — find dialogue or internal thoughts showing she doesn’t love the suitor or finds their values incompatible.
Trauma or past experience — look for backstory (abuse, bereavement, previous bad relationship) that makes marriage unappealing.
Political/feminist statement — the author may use her choice to critique social norms; examine narrator’s commentary and thematic language.
Economic or practical reasons — sometimes characters refuse marriage because of finances, inheritance rules, or obligations to others.
Religious or philosophical beliefs — check for explicit statements about vows, celibacy, or life purpose.

How you can support an answer from the text:

Quote direct lines where Janette explains or refuses marriage.
Point to actions that reinforce the refusal (leaving a suitor, pursuing work).
Connect those quotes/actions to the story’s themes or historical context.
Note the narrator’s tone and other characters’ reactions.

Send the title/author (or paste the passage) and I’ll give a specific, text‑based explanation with quotes and analysis.
