I think you could perhaps get that someone may have helped him and looked after him in a way that he didn't need to be very independent, George is always helping him and telling him things they don't have.. This could be down to his mental health but also down to his childhood. Just what I got from it..hope it helped a little :)
Itβs on the book
Lennie's childhood in "Of Mice and Men" was marked by a lack of stable family support, care from his aunt who eventually passed away, and struggles due to his mental disability. His behavior indicates isolation and a longing for connection, reflecting the hardships of his upbringing during the Great Depression. These factors deeply influence his character and relationships in the story.
