i can hardly type a complete sentence that illustrates what i want to convey for my Literature assignment. yet i've been stuck here in the library since 3(it's been 3 looong hours!). hence the term "nerdic" (coined by yours truly). fine, say it's a result of me being friendless that books are my only companions.
i dislike heart of darkness. grrrr.
