Quote Detail

Slim has just asked, with unforced friendliness, whether George and Lennie travel together. After George confirms it, Slim offers this gentle generalization as response.

The hedge 'I don't know why' followed by the modal 'Maybe' performs the speaker's intellectual humility—Slim raises the question rather than pronouncing on it, the syntactic opposite of the boss's earlier accusatory certainties. The universalizing scope ('the whole damn world') paired with a strikingly modern psychological diagnosis ('scared of each other') gives the line the weight of secular wisdom; Slim arrives at an existential observation by reasoning from a single empirical anomaly (two men traveling together) outward.

Support a thesis that Slim functions as the novel's ethical observer whose gentle inferences from particulars articulate what the narrator otherwise demonstrates—this line transforms the boss's earlier suspicion of George and Lennie's bond into evidence of a generalized human pathology, situating their friendship as critique rather than curiosity.
