Yeah but it's the whole age thing, I'm 15 but can think straight. Her being 15 makes no difference, it's to do with her surroundings and family and friends that make her like she is, not how long she's been walking on this planet.
Inspiring oration indeed. I believe the commentary on age was more a distinguishment of how she is only 15 and yet she already has acquired the ubiquitous obsession and prioritization of money.
Why should rich people be weird? Rich people can also be nice. And I do not "believe" in love (whatever the hell that is supposed to mean). Love is a biological concept that helps us reproduce, so that's that.
