A note to the reader: I purchased these letters at the bazaar outside the gates of the Bagram Air Base in Afghanistan in 2006. I was working that winter for a humanitarian organization in Kabul. The bazaar was a row of shipping containers and battered tarpaulins along the road to the base’s fortified gates. Military vehicles rumbled past, splattering sleet and mud. Inside the containers, merchants warmed their chapped hands before makeshift propane heaters and haggled over cold piles of misappropriated objects.
