In this time period if you were traveling with another guy most people looked at you funny; however, George and Lennie did not care because they had a brotherhood. Brotherhood is when you and your non-related friend stick together no matter what is happening and you will always be their for the other person, for good or bad. In this novel you can feel as though there was a lot of brotherhood relationship quotes but this one seems to stick out a lot. "Because I got you to look after me and you got me to look after you (Steinbeck 14)." This quote means that since there brotherhood is so strong they will both be there for each other no matter what. Even if they are mad at other people in the novel they still stick together. So with the theme of brotherhood the next quote is basically how George feels about his life after he had to kill Lennie. "The friendship blows like a breath of love through the lonely world of the ranch hands, who are moved by it to think all things possible, but it inspires the hate of the cowardly boss's son and proves in the end an ill-fated relationship among workers destined for loneliness"(Dusenbury 346). This quote starts out by saying that they have a friendship that is really strong and they will always be there for each other no matter where they work. Then the quote ends by saying that George is basically going to be lonely now that he does not have Lennie there by his side all the time. Out of all of the themes in the book there is a strong sense of brotherhood.
