Answer:
True, George is definitely the caretaker of the child like Lennie. George does more than enough back for George, otherwise they wouldn't still travel together. Lennie is a friend for george so he doesn't ever get lonely. Another thing Lennie does for George is providing a job. Many people would be willing to hire George and Lennie because Lennie is HUGE and is very hard working. They both give one another what they need to have a great friendship and a way of surving through the rough times.
