“A guy sets alone out here at night, maybe readin’ books or thinkin’ or stuff like that. Sometimes he gets thinkin’, an’ he got nothing to tell him what’s so an’ what ain’t so. Maybe if he sees somethin’, he don’t know whether it’s right or not. He can’t turn to some other guy and ast him if he sees it too. He can’t tell. He got nothing to measure by. I seen things out here. I wasn’t drunk. I don’t know if I was asleep. If some guy was with me, he could tell me I was asleep, an’ then it would be all right. But I jus’ don’t know.”
– John Steinbeck
