““People who do this type of work talk about the rupture we feel on our return, an irreconcilable invisible difference between us and others. We talk about how difficult it is to assimilate, to assume routine, to sample familiar pleasures. The rift, of course, is not in the world: it is within us…The world is a hard place -- a beautiful place, but so too an urgent one. ... Once that urgency takes hold, it never completely lets go.””
