Why does curley pick fights with big guys in mice and men?

curley is named the disrespectful guy in the novel because he lacks important traits that u need to suceed in life. He is very rude when he communicates with others, always a rude perosn to his wife, and is described as a "terrible person". On the other hand, Slim is the opposite of curley. Slim is very generous, loving, smsrt, carming, always willing to help anyone who has trouble in their lifes, does really well working, and is an all around respectful person. Also this is an off topic statment, but anyone has flappy birds, my god its such an additing game, if those of u dont have, get it. Its really addicting
