Metal

[dukealien]

Cold gleaming silver
imprints on the skin
above your heart.

Four years of iron
wither like a pick up
left to rust.

Not to spoil anyone else's take/interpretation, only expose my own (ignorant) one...

I see the badge and the service pistol - wives of policemen complain (including those who are officers themselves) about "always that iron between us."  As musical accompaniment, something resembling "I walk the line."

But I could be  utterly mistaken (g).  Very good:  the rhythm, which is perfect.  Tiny suggestion:  I'm reading "pickup" for "pick up," as in light truck.

Beautiful.
