1- Hands (they are husbands):

Black Hat hands are cold and soft, long and delicate fingers with sharp claws.

Flug hands are warm and coarse, marked with scars, cuts and burns, occupational hazards.

When they intertwine, Flug shares his warmth, Black Hat takes it gladly, letting his temperature adjust to his doctors.   

When they caress, those cold and fearsome hands are gentle, that cold a relief for old wounds. 

In those hands, so different, identical rings shine.
