“ Say you've just read Faulkner's 'Barn Burning'. Like the son in the story, you've sensed the faults in your father's character. Thinking about them makes you uncomfortable, left alone you'd probably close the book and move on to other thoughts. But instead you are taken in hand by a tall, brooding man with a distinguished limp who involves you and a roomful of other boys in the consideration of what it means to be a son. The loyalty that is your duty and your worth and your problem. The goodness of loyalty and its difficulties and snares, how loyalty might also become betrayal - of the self and the world outside the circle of blood. You've never had this conversation before, not with anyone. And even as its happening you understand that just as your father's troubles with the world - emotional frailty, self-doubt, incomplete honesty - will not lead him to set it on fire, your own loyalty will never be the stuff of tragedy. You will not turn bravely and painfully from your father, as the boy in the story does, but foresake him, without regret. And as you accept that separation, it seems to happen; your father's sad, fleshy face grows vague, and you blink it away and look up to where your teachers leans against his desk, one hand in a coat pocket, the other rubbing his bum knee as he listens desolately to the clever bore behind you saying something about bird imagery. ”
