SHOPPING It is important to tie your shoelaces--both shoelaces--before going into the pawn shop. And to carry only old bills, used till they have a softness like cloth. Take a friend. Just inside the door there are micrometers for measuring what you find. In a corner, there is talk cool as a silver flute to be had for next to nothing. Over there, a set of memories of red hair, slightly out of chronological order. A shelf containing the possibilities of loss: numbness, sorrow, fury, relief. Behind the counter, more talk--is flight too late, does the future have more pasts than the past has futures? A box with a broken latch is filled with a jumble of pages torn from calendars, each with at least one name, some with an X drawn through the date. As you leave, untie your shoelaces, check your pockets to make sure you are taking nothing home that is not yours.
