| Quote #1 "God, you’re a lot of trouble," said George. "I could get along so easy and so nice if I didn’t have you on my tail. I could live so easy and maybe have a girl." |
At this point, it seems George grasps that he’s more in Lennie’s boat now: he can’t have the kind of stability represented by having a girl, but the next best thing is having a job.
| Quote #2 "Seems like Curley is cockier’n ever since he got married." |
From this tidbit, it seems that Curley’s performance around the ranch is to impress his wife. Perhaps she’s more than an object, and really means something to him.
| Quote #3 OLD MAN [CANDY] "Well, that glove’s fulla Vaseline." |
It’s pretty clear here that Curley’s marriage, in his mind, is a performance to impress the other guys at the ranch. Curley isn’t trying to impress his wife; he’s trying to use her (and his supposed relations with her) as a tool to prove how very manly he is. Nobody who respected his wife and felt secure in his relationship would need to spread talk like that around to the guys.
