One life buoy, two, ah, creative forces. On the front, poetry: the line "Sheltered with red sex & the scale of moonshine lips" made me think of Bukowski. The American spelling of 'favour' made me wonder whether the author is a visiting international student over at the UEA's creative writing department.
On the back, however, an approach much closer to my black heart: as well as the inherent dark irony of the words being scrawled across something intended to preserve life, the sheer no-nonsense minimalist bleakness of them are far more powerful: "Just jump. Nobody cares."
