- Teen Pregnancy: Implied, as Geneva tells Sabrina, "But I wasn't a woman, I was a child, and your grandmere knew that." when asked why the latter was raised by Claudine.
- Trailers Always Lie: The trailers made it sound like a comedy about uptown meeting downtown, when in reality the movie was more of a dramedy.
- Uptown Girl: Sort of. Jason is more of a self-made person, whereas even though Sabrina has a high paying job, she came from money.
