I also love this passage from the short story, which just highlights lips and hands like crazy:
"They seized each other by the shoulders, hugged mightily, squeezing the breath out of each other, saying, son of a bitch, son of a bitch, then, and easily as the right key turns the lock tumblers, their mouths came together and hard, Jack's big teeth bringing blood, his hat falling to the floor, stubble rasping, wet saliva welling . . . and still they clinched, pressing chest and groin and thigh and leg together, treading on each other's toes until they pulled apart to breathe and Ennis, not big on endearments, said what he said to his horses and daughters, little darlin." And later on: "[Jack's] shaking hand grazed Ennis's hand, electrical current snapped between them."
And--lest I forget--their brief fight on BBM just before coming down, when Jack elbows Ennis, making his nose bleed, and then holds and tries to comfort him before Ennis punches him on the side of the face. This difficult combination of tenderness and violence--wow.
