Leather Coin Purse 

I’m a leather coin purse
rubbed glossy with sweat
that rains from shaking fingers.
 
I have a silver clasp,
slightly tarnished but no less strong—
sewn into my skin and shadow,
gleaming with the secret between my cells
only the maker knew.
 
I am a leather coin purse,
an old, black pocket.
I’ve sat and dreamed in sock drawer bottoms,
beach sidewalks, on hotel beds
next to shaking, sweaty fingers
that stitched the sounds of crying into my seams.
