It's hard to be oneself. Mostly because of the fact that to be oneself requires you to know yourself.
'Nosce te ipsum', as the Romans used to say. (Though to be fair they probably copied it from the Ancient Greeks. If you know your art history, you'd know they pulled that kind of copycat crap all the time!)
But the girl who wears Sass & Bide doesn't have that problem because she figured out who she is a long time ago. She's the smart one that knows her shit and handed in a perfect paper before the exam was even halfway through.
Yeah, she's a bit of a show-off, but hey, you gotta work what you got.
