It's a Start...

Mouse Trap

Nobody builds a bulwark with a hinge
a trap door.
I can't help it--my architect is mad.
Head--steel trap.
Body--admirably constructed.
Even hands and feet, face hair nails are
alright.
But my heart? Oh, my heart...
Humane? Yes.
You can get in to find the nicest cheese
a prize, you think.
Getting out, though...

I've experienced too much death
for it to still be winter...
