Every word in this paragraph begins with "they." Bradbury does this purposefully. What is the effect? "They stood as if someone had driven them, like so many stakes, into the floor. They looked at each other and then looked away. They glanced out at the world that was raining now and raining and raining steadily. They could not meet each other’s glances. Their faces were solemn and pale. They looked at their hands and feet, their faces down."
