If I had eight hours to chop down a tree, I'd spend six hours sharpening my ax.
Except they had never had a fight. Not in the sense meant by people paid to fight or die. Pushing and shoving at the schoolyard gate or on the sidewalk outside the soda shop or late at night after a start-of-summer keg party was as far from fighting as two fat guys tossing lame spirals in the park were from the Superbowl.
