no one is around , and i imagine this whole city is under ocean water-i imagine i 'm scuba diving , and it 's not really all that hard to do because it 's dark and desolate and my skin is kind of wet from sleeping under the down comforter herr silverman threw over me and also from freaking out , which maybe i 'm still doing , although i 'm trying not to think about yesterday-how choosing life might have been a mistake .
