I suppose that I'm a combination of them, although the following two are probably most like me:
The All-the-Timer/Compulsive/Voracious/Anything Goes Reader. Wherever you go, whatever you do, there's a book with you. It doesn't matter what it is, really, so long as there are pages with words on them, or an e-reader with words on it. We can't really suggested anything here because you took it with you to the grocery store or subway or library or laundromat or coffee shop, and you're standing in line or sitting down and reading it right now.
The Cross-Under. You are a grown-up who reads Y.A. or kids books, or a kid who reads adult books, and there is a place for you in society, finally. Your existence acknowledged after so many years, you no longer have to feel shame at your questionable reading habits but can instead bask in the admiration of book blogs and feel a part of the vanguard. You are not ruled by categories; you are a free thinker. When you were in elementary school a librarian told you a book was "Too old for you." You read it anyway, and there's been no going back. - I should say that I'm almost 30 and totally love reading YA books.
