"Outside, a soldier spits out / his cigarette as footsteps fill the square like stones / fallen from the sky. May / all your Christmases be white / as the traffic guard unstraps his holster." Ocean Vuong shares poems from his debut collection, Night Sky With Exit Wounds (Copper Canyon Press, 2016), and speaks about the oral tradition of his family and his personal ties to the Vietnam War for a series on PBS NewsHour.
