Fragility and power - the poet suggests that paper, which is a fragile tissue, has the power to alter and control our existence. Tissue paper alters our view of things; paper is used to record powerful, even sacred, knowledge and information. This leads the poet to speculate that buildings are drawn on thin architect paper; landmarks and geographical features become see-through when they are printed on maps; shop receipts have the power to control our lives, though they are worthless.
