When crooks says a guy go nuts if he ain't got nobody whom is he talking about?

In John Steinbeck's "Of Mice and Men," Crooks is referring to the loneliness and isolation experienced by itinerant workers during the Great Depression. He suggests that without companionship or meaningful relationships, a person can lose their sanity. The statement highlights the importance of human connection and the psychological toll of solitude, particularly for marginalized individuals like Crooks himself.
