I wanted to tell them that, in Kabul, we snapped a tree branch and used it as a credit card. Hassan and I would take the wooden stick to the bread maker. He'd carve notches on our stick with his knife, one notch for each loaf of naan he'd pull for us from the tandoor's roaring flames. At the end of the month, my father paid him for the number of notches on the stick. That was it. No questions. No ID.
