" I'll tell ya one thing -- the jail house is jus' a kind a way a drivin' a guy slowly nuts. See? An' they go nuts, an' you see 'em an' hear 'em, an' pretty soon you don' know if you're nuts or not. When they get to screamin' in the night sometimes you think it's you doin' the screamin'--an' sometimes it is. "

― John Steinbeck , The Grapes of Wrath
