Hanstark thought it was going to be easy. "Mr. Nest, it is a well known fact that no one can walk in mid-air. Is that not true?"
Nest took a deep drag on his cigarette and blew the smoke out of his nostrils. "Shore."
"Then if I were to walk out above your pass you'd have to admit there is no pass."
"Reckon so."
Hanstark began to walk in the direction of Nest's "cliff." Nest jumped to his feet and grabbed the official psychiatrist by the arm.
"What're you tryin' to do," Nest said angrily, "kill yourself?"
Hanstark shook free of his grasp. "Mr. Nest, I am not going to kill myself. I am merely going to walk in that direction." He pointed to where the cliff was supposed to be. "To you it will look as if I were walking in mid-air."
Nest dropped his hands to his sides. "Shucks, I don't care if you kill yourself. It's just that it's liable to make the cattle nervous."
Hanstark gave him a cold glare and began to walk. He took three paces and stopped. "You see, Mr. Nest. There is no cliff."
Nest looked at him and laughed. "You just take one more step and you'll find there is a cliff!"
