Ali and Baba grew up together as childhood playmates – at least until polio crippled Ali's leg – just like Hassan and I grew up a generation later. Baba was always telling us about the mischief he and Ali used to cause, and Ali would shake his head and say, "But, Agha sahib, tell them who was the architect of the mischief and who the poor laborer?" Baba would laugh and throw his arm around Ali.

But in none of his stories did Baba ever refer to Ali as his friend. (4.2-3)

But we were kids who had learned to crawl together, and no history, ethnicity, society, or religion was going to change that either. I spent most of the first twelve years of my life playing with Hassan. Sometimes, my entire childhood seems like one long lazy summer day with Hassan, chasing each other between tangles of trees in my father's yard, playing hide-and-seek, cops and robbers, cowboys and Indians, insect torture – with our crowning achievement undeniably the time we plucked the stinger off a bee and tied a string around the poor thing to yank it back every time it took flight. (4.6)

Hassan's favorite book by far was the Shahnamah, the tenth-century epic of ancient Persian heroes. He liked all of the chapters, the shahs of old, Feridoun, Zal, and Rudabeh. But his favorite story, and mine, was "Rostam and Sohrab," the tale of the great warrior Rostam and his fleet-footed horse, Rakhsh. Rostam mortally wounds his valiant nemesis, Sohrab, in battle, only to discover that Sohrab is his long-lost son. Stricken with grief, Rostam hears his son's dying words:

If thou art indeed my father, then hast thou stained thy sword in the life-blood of thy son. And thou didst it of thine obstinacy. For I sought to turn thee unto love, and I implored of thee thy name, for I thought to behold in thee the tokens recounted of my mother. But I appealed unto thy heart in vain, and now is the time gone for meeting...

"Read it again please, Amir agha," Hassan would say. Sometimes tears pooled in Hassan's eyes as I read him this passage, and I always wondered whom he wept for, the grief-stricken Rostam who tears his clothes and covers his head with ashes, or the dying Sohrab who only longed for his father's love? Personally, I couldn't see the tragedy in Rostam's fate. After all, didn't all fathers in their secret hearts harbor a desire to kill their sons? (4.23-24)

We chased the Kochi, the nomads who passed through Kabul on their way to the mountains of the north. We would hear their caravans approaching our neighborhood, the mewling of their sheep, the baaing of their goats, the jingle of bells around their camels' necks. We'd run outside to watch the caravan plod through our street, men with dusty, weather-beaten faces and women dressed in long, colorful shawls, beads, and silver bracelets around their wrists and ankles. We hurled pebbles at their goats. We squirted water on their mules. I'd make Hassan sit on the Wall of Ailing Corn and fire pebbles with his slingshot at the camels' rears. (4.7)

The curious thing was, I never thought of Hassan and me as friends either. Not in the usual sense, anyhow. Never mind that we taught each other to ride a bicycle with no hands, or to build a fully functional homemade camera out of a cardboard box. Never mind that we spent entire winters flying kites, running kites. Never mind that to me, the face of Afghanistan is that of a boy with a thin-boned frame, a shaved head, and low-set ears, a boy with a Chinese doll face perpetually lit by a harelipped smile.

Never mind any of those things. Because history isn't easy to overcome. Neither is religion. In the end, I was a Pashtun and he was a Hazara, I was Sunni and he was Shi'a, and nothing was ever going to change that. Nothing. (4.4-5)

We saw our first Western together, Rio Bravo with John Wayne, at the Cinema Park, across the street from my favorite bookstore. I remember begging Baba to take us to Iran so we could meet John Wayne. (4.8)

Then, Baba and I drove off in his black Ford Mustang – a car that drew envious looks everywhere because it was the same car Steve McQueen had driven in Bullitt, a film that played in one theater for six months. (4.10)

I read it to him in the living room by the marble fireplace. No playful straying from the words this time; this was about me! Hassan was the perfect audience in many ways, totally immersed in the tale, his face shifting with the changing tones in the story. When I read the last sentence, he made a muted clapping sound with his hands.

"Mashallah, Amir agha. Bravo!" He was beaming.

"You liked it?" I said, getting my second taste – and how sweet it was – of a positive review.

"Some day, Inshallah, you will be a great writer," Hassan said. "And people all over the world will read your stories."

"You exaggerate, Hassan," I said, loving him for it.

"No. You will be great and famous," he insisted. (4.52-57)

That Hassan would grow up illiterate like Ali and most Hazaras had been decided the minute he had been born, perhaps even the moment he had been conceived in Sanaubar's unwelcoming womb – after all, what use did a servant have for the written word? But despite his illiteracy, or maybe because of it, Hassan was drawn to the mystery of words, seduced by a secret world forbidden to him. I read him poems and stories, sometimes riddles – though I stopped reading those when I saw he was far better at solving them than I was. (4.12)

One day, in July 1973, I played another little trick on Hassan. I was reading to him, and suddenly I strayed from the written story. I pretended I was reading from the book, flipping pages regularly, but I had abandoned the text altogether, taken over the story, and made up my own. Hassan, of course, was oblivious to this. To him, the words on the page were a scramble of codes, indecipherable, mysterious. Words were secret doorways and I held all the keys. (4.25)

As always, it was Rahim Khan who rescued me. He held out his hand and favored me with a smile that had nothing feigned about it. "May I have it, Amir jan? I would very much like to read it." Baba hardly ever used the term of endearment jan when he addressed me. [...]

An hour later, as the evening sky dimmed, the two of them drove off in my father's car to attend a party. On his way out, Rahim Khan hunkered before me and handed me my story and another folded piece of paper. He flashed a smile and winked. "For you. Read it later." Then he paused and added a single word that did more to encourage me to pursue writing than any compliment any editor has ever paid me. That word was Bravo. (4.43-45)
