This text belongs to George Bernard Shaw's Pygmalion, Act 2. Mrs. Pearce is telling Higgins not to tempt a girl who should think about her future, at which Higgins states those things about Eliza's age. Eliza responds that she is a good girl, so she does not want any of those things.
She is insulted and tells him she doesn't want any of those things; she is a "good girl."
