....there is an ending [to Infinite Jest] as far as I'm concerned. Certain kind of parallel lines are supposed to start converging in such a way that an "end" can be projected by the reader somewhere beyond the right frame. If no such convergence or projection occured to you, then the book's failed for you.
David Foster Wallace...and suddenly it occurred to him that the birds, whose twitters and repeated songs sounded so pretty and affirming of nature and the coming day, might actually, in a code known only to other birds, be the birds each saying 'Get away' or 'This branch is mine!' or 'This tree is mine! I'll kill you! Kill, kill!' Or any other manner of dark, brutal, or self-protective stuffโthey might be listening to war cries. The thought came from nowhere and made his spirits dip for some reason.
