If I were a book,
what would my cover lead you to believe?

Colorful knee socks - a bit quirky.
Nose ring - acquired during a brief rebellious phase.
Purple hair - craving attention.
Lack of eye contact - lacking self confidence, socially awkward.
Chipped nail polish - not quite a girly-girl or a tomboy
Combat boots - attempting to seem edgy.

Maybe your assumptions are right.
But you'll never know until you read the book.
