Home is what we know we ought to want but can't really take. America is not so much a home for anyone as a universal dream of home, a wish whose attraction depends upon its remaining at the level of a wish. The movies bring the boys back but stop as soon as they get them back; for home, that vaunted, all-American ideal, is a sort of death, and an oblique justification for all the wandering that kept you away from it for so long.
