a. "the father raised his head and banged on the wheel, struck it."
b. "then abruptly he swung around, clambered back into the cabin of his truck and started the engine with a roar at which the others fell back, their attitudes slackening in relief, but then he wheeled the truck around and parked it squarely across the highway so no traffic could get past in either direction."
c. "he seemed deliberately to split in the direction of those who stood watching in growing frustration."
d. "'work goes better after a little rest,' the elder replied, and demonstrated by lowering himself on to his haunches and squatting there on the roadside like an old bird on its perch or a man waiting to be shaved by a roadside barber."
