After first seeing the film, my daughter asked my father, who spent his childhood in a small city in the Berkshires, if the freedom the film depicts was the freedom he had, if childhood once looked and sounded like that. She wondered if this sort of unobserved life was as he remembered it, if he might, just as these boys did, have set off for days without parental concern. He told her, with amusement, that he was, in fact, expected to be home for dinner, but beyond that, yes, he could roam, without surveillance. (He quibbled with the 12-year-olds’ smoking.)
