The author of the short story had a very short and punchy syntax to
the story. For example, on page 24, while talking to the officer his
sentences were very short. The conversation was:
"Leave me alone."
"Are you a citizen of the United States?"
"Yes."
"Can you prove it?"
"No. No, I can't."
This part of the conversation shows by using this syntax, the author
is trying to show that he is aggravated with the patrol.
