This shows they are similar in the way they are both itinerant workers. However they differ with appearance: George is explained to have ‘sharp features’, and Lennie to be his opposite ‘shapeless of face’. Steinbeck uses their appearance to show how completely different they are with everything, George has a sharp, quick mind, while on the other hand Lennie is rather simple minded. Steinbeck presents George and Lennie’s relationship very much like that of a father and sons.
George looks after Lennie’s work card as George knows Lennie well enough not to trust him with it: “think I’d let you carry your own work card? ” George also looks out for Lennie and tries to protect him- ‘you never oughta drink water when it ain’t running’, which is evidence to show he is like a father, advising Lennie. Steinbeck emphasises the theme of George and Lennie being like a father and son further by George praising Lennie to build Lennie’s self esteem: “Good boy, that’s it”.
