This scene is very important because it describes the loneliness of most of the workers at the time! It also is good character development for Lennie and George.
Slim and George came into the darkening bunkhouse together. Slim reached up over the card table and turned on the tin-shaded electric light. Instantly the table was brilliant with light, and the cone of the shade threw its brightness straight downward, leaving the corners of the bunkhouse still in dusk.
Slim sat down on a box and George took his place opposite. "It wasn't nothing," said slim. I would of had to drowned most of em anyways. No need to thank me about that." George said, It wasn't much to you, maybe, but it was a hell of a lot to him. Jesus Christ, I don't know how were gonna get him to sleep in here. He'll want to sleep right out in the barn with 'em. We'll have trouble keepin' him from getting right in the box with them pups."
"It wasn't nothing," Slim repeated. "Say, you sure was right about him. Maybe he ain't bright, but i never seen such a worker. He damn near killed his partner buckin' barley. There ain't nobody can keep up with him. God almighty I never seen such a strong guy" George spoke proudly. "Jus' tell Lennie what to do an' hell do it if it don't take no figuring. He can't think of nothing to do himself, but he sure can take orders."
Slim moved back slightly so the light was not on his face. "Funny how you an' him string along together." It was Slim's calm invitation to confidence. "Whats funny about it?" George demanded defensively.
"Oh i dunno. Hardly none of the guys ever travel together. I hardly never seen two guys travel together. You know how the hands are, they just come in and get their bunk and work a month, and then they quit and go out alone. Never seen to give a damn about nobody. It jus' seems kinda funny a cuckoo like him and a smart little guy like you travelin together."
"He ain't no cuckoo," said George. "He's dumb as hell, but he ain't crazy. ain't crazy. An' I ain't so bright neither, or I wouldn't be buckin' barley for my fifty and found. If I was bright, if i was even a little bit smart. i'd have my own little place, an' I'd be bringin' in my own crops, stead of doin' all the work and not getting what comes up outta the ground." George fell silent. He wanted to talk. Slim neither encouraged or discouraged him. He just sat back quiet and receptive.
