e. to criticize people who think only about the past

Presiding over a formica counter,

plastic Mother and Child magnetized

to the top of an ancient register,

the heady mix of smells from the open bins

of dried codfish, the green plantains

hanging in stalks like votive offerings,

she is the Patroness of Exiles,

a woman of no-age who was never pretty,

who spends her days selling canned memories

while listening to the Puerto Ricans complain

that it would be cheaper to fly to San Juan

than to buy a pound of Bustelo coffee here,

and to Cubans perfecting their speech

of a “glorious return” to Havana –where no one

has been allowed to die and nothing to change until then;

to Mexicans who pass through, talking lyrically

of dólares to be made in El Norte- all wanting the comfort

of spoken Spanish, to gaze upon the family portrait

of her plain wide face, her ample bosom

resting on her plump arms, her look of maternal interest

as they speak to her and each other

of their dreams and their disillusions-

how she smiles understanding,

when they walk down the narrow aisles of her store

reading the labels of packages aloud, as if

they were the names of lost lovers: Suspiros,

Merengues, the stale candy of everyone’s childhood. She spends her

Slicing jamón y queso and wrapping it in wax paper

Tied with string: plain ham and cheese

that would cost less at the A&P, but it would not satisfy

the hunger of the fragile old man lost in the folds

of his winter coats, who bring her lists of items.

that he reads to her like poetry, or the others,

whose need she must divine, conjuring up products

from places that now exist only in their hearts-

closed ports she must trade with.
