Yesterday is all that does count

From No Country for Old Men by Cormac McCarthy:

He looked at her. After a while he said: It's not about knowin where you are. It's about thinkin you got there without takin anything with you. Your notions about startin over. Or anybody's. You dont start over. That's what it's about. Ever step you take is forever. You cant make it go away. None of it. You understand what I'm saying?

I think so.

I know you dont but let me try it one more time. You think when you wake up in the mornin yesterday dont count. But yesterday is all that does count. What else is there? Your life is made out of the days it's made out of. Nothin else. You might think you could run away and change your name and I dont know what all. Start over. And then one mornin you wake up and look at the ceilin and guess who's laying there?

I read in the papers here a while back some teachers come across a survey that was sent out back in the thirties to a number of schools around the country. Had this questionnaire about what was the problems with teachin in the schools. And they come across these forms, they'd been filled out and sent in from around the country answerin these questions. And the biggest problems they could name was things like talkin in class and runnin in the hallways. Chewin gum. Copyin homework. Things of that nature. So they got one of them forms that was blank and printed up a bunch of em and sent em back out to the same schools. Forty years later. Well, here come the answers back. Rape, arson, murder. Drugs. Suicide. So I think about that. Because a lot of the time ever when I say anything about how the world is goin to hell in a handbasket people will just sort of smile and tell me I'm gettin old. That it's one of the symptoms. But my feelin about that is that anybody that cant tell the difference between rapin and murderin people and chewin gum has got a lot bigger of a problem than what I've got. Forty years is not a long time neither. Maybe the next forty of it will bring some of em out from the ether. If it aint too late.
