Ma joad wanted to know how long it would take to get to California. what was tom's answer?

"I dunno," he said. "Two weeks, maybe ten days if we got luck. Look, Ma, stop your worryin'. I'm a-gonna tell you somepin about bein' in the pen. You can't go thinkin' when you're gonna be out. You'd go nuts. You got to think about that day, an' then the nex' day, about the ball game Sat'dy. That's what you got to do. Ol' timers does that. A new young fella gets buttin' his head on the cell door. He's thinkin' how long it's gonna be. Whyn't you do that? Jus' take ever' day."
