Well, I never seen one guy take so much trouble for another guy. I just like to know what your interest is.
Chapter 2 · The Boss
Context
Continuing his interrogation of George, the boss states explicitly that he has never witnessed companionship between migrant workers and therefore distrusts it.
Analysis
The construction 'never seen one guy take so much trouble for another guy' uses empirical observation as moral standard—what has not been seen cannot be legitimate. The repeated indefinite 'one guy... another guy' reduces the human bond to interchangeable units, the same flattened idiom Slim will later use ('Ain't many guys travel around together') but in Slim's mouth tinged with wonder rather than suspicion. The boss's diction confirms that on the ranch, atypical behavior is always read as predatory before it is read as decent.
How to Use in Essay
Support a thesis that the novella's central tragedy is sociological rather than personal—the boss's incomprehension establishes that an entire economic order has rendered friendship statistically improbable, which sets up Slim's later observation as elegy for what the system has destroyed.
