remember wen writing anything link it to the book and also on America at the time i.e crooks is dicriminated cos he's black in america racism was so dominant blah blah blah......
Dreams- leonine and George tO own their own land and 'tend to the rabbits'
Loneliness - candy only has his dog as a companion in the beginning of the novel. Curlews wife's the only woman. The ranch lifestyle was very lonely, migrant workers would travel alone
Handicaps- all of the main characters have a handicap- mental or physical.
George's is different but still a handicap as he is dragged down but Leanne but this shows he isnresponsible as he keeps his promise to aunt Clara
Discrimination- curlews wife 'tart' '********' 'tramp' the only woman on the ranch. Doesn't get named - seen as possession to Curley. Crooks- segregated because he is black
Relationships - Leanne relies on George as g is leader. They have a paternal relationship but I'm some ways George reliesn lennie for companionship
Loads more but those are the main ones :) sorry its brief!
