“This is awesome, bro,” Buff said.

“Yes,” I said. “Awesome.”

The fantasy lasted three days. Each night I was the one who called “time” and said we had to go. Each night got longer. I’m afraid of what might have happened had Buff never thrown that rock, the one that brought everything down. We were so close already, another day and maybe we would’ve stayed forever. Maybe we would’ve disappeared, like I wanted to back then, when I was young. Of course, things never work out the way you want them to. And then all you do, the rest of your life, is dream about what would’ve happened, or could’ve happened, had you done what you wanted to do in the first place.

In his defense, that rock was probably the biggest the gravel roof had to offer. In his defense, we should’ve hurled that rock months earlier, when the summer had first started, when I first met Buff. In his defense, no rock had ever glanced off a windshield, not like that, and really, what an odd set of circumstances, to have that little girl rounding third base in the park across the street at just the right time for the rock to go sailing into her temple, breaking her little head open, sending her chest-first into the concrete, her feet kicking up behind her, one lone white shoe cartwheeling over her body, landing somewhere up near her head, which had already begun to spout blood.

I remember this all as individual events. In my mind I can freeze each frame. Like when Buff and I turned to look at each other. Like when I saw Buff, not smiling but somehow shrugging, like he’d known this was going to happen, like he’d known something was going to happen to spoil everything.

They hadn’t even seen us yet, the family of the little girl, the gangbangers across the street. They hadn’t even called out like I remember them doing, “Hey, up there! Look, there they are! There’s those little fuckers!” None of this had even happened yet when Buff turned to me and said, “Sorry.” I wonder what he saw in my face. I wonder if he knew it wasn’t just his fault, that we were accomplices, friends.

In another moment the gangbangers were on the roof. I was punched in the stomach hard enough to make my back ache.

“Who threw the rock?” one of them asked me.

I looked to Buff. “Me,” he said. I am aware now that the noble thing would’ve been for me to say that I had done it, that I had thrown the rock. And I can see the nobility in Buff speaking up — even though he had done it, he didn’t have to say he had done it. At the time, though, the thought of taking the blame didn’t even cross my mind. I just watched one of the gangbangers approach Buff and without any warning, a windup, a step, a twist of the body, punch Buff square in the side of the face.

Buff didn’t make a sound. His knees buckled. He looked down. The side of his face was red. But he didn’t whimper or cry. When the kid who punched Buff turned, I saw that it was Junebug, the kid Buff had claimed was his cousin, the ugly kid.

They tore our house apart. They kicked in the flimsy walls. I hadn’t realized how weak the structure actually was. We’d sat in the house during rain, but we’d never have survived any kind of strong wind. It was only a matter of time.

I was dragged across the roof, handed down the air-conditioning ducts. Once on the ground I heard sirens, saw the flashing lights of ambulances and fire trucks. Police officers were pulling up. They saw Buff and me being led down the street in opposite directions. They saw that we’d been roughed over, beaten. They didn’t stop any of the gangbangers to ask questions. We were on our own then, and for a split second I had a flashback to when Buff had first suggested that we could build a house, a flashback to when I’d first called up to Buff, “Hey, how’d you get up there?” And, as I was presented to my father and yanked by my collar into the house, I longed for that feeling again. The feeling that I was all alone, that I was entirely free.

I’ve had other moments, since then. When I graduated college, for about five seconds I felt free. Or when I rode my first motorcycle down the alley behind my house, for about ten seconds I felt free. Then I realized I had to turn. But up there on the roof, when I was alone with Buff, I knew it, that it was all us; our lives were what we made of them. Never again have I felt as free as I did then.

Years after the pierogi factory incident I heard that Buff had been shot dead. This was in high school, my sophomore year. I was hanging out with friends in Barrett Park, where we played ball and drank beer. Ramiro said it. He always had the neighborhood news: “Hey, did you guys hear Buffster from the Latin Counts got killed? A drive-by, bro, right there on Wood Street. Got blasted in the head. Dead on arrival.”

“You mean bald-headed Buff?” I asked. “Short guy, blue eyes?”

“Yeah,” Ramiro said. “You knew him?”

“Yeah,” I said. “We grew up together.”

“No you didn’t, bullshitter,” Alex, another in our group, said.

“No, I did,” I told them. “One summer me and him, we built a house. Over there on top of the old pierogi factory. You should’ve seen it. We were going to live there.”

I grew up on Eighteenth Street and Throop, in the heart of Chicago. To the east, beyond the Dan Ryan Expressway, beyond the steeple of Providence of God Church, and beyond the no-man’s land that was the “darkside,” a stretch of neighborhood laced with forgotten Illinois-Continental railroad tracks and collapsing smokestacks, a place said to be inhabited by the most ruthless Mexican street gang in Chicago, the Villa Lobos, was the lake. To the north were the Puerto Ricans, who were rumored to surpass the Villa Lobos in ruthlessness, said to be willing to shoot you in front of a church or in front of family, sins the Mexican gangs swore against. And then beyond them, farther north, were the whites, in a dreamland accessible only by the Chicago L, and even at that a place you glimpsed momentarily — redbrick houses, wrought-iron fences, tree-lined streets — then left, swallowed by the subway if you were on the Douglas-Park B, or forced to watch it all fade from view if you rode the elevated Ravenswood A.

The blacks were to the south. They were unfathomables. Things we didn’t understand went on down there. Killings were indiscriminate. And to the west was the sunset, that’s all I ever knew about the west, when evening would come and the sun would hit that point at the horizon where it flared up the long neon glass corridor of Eighteenth Street as if each panaderia, taco joint, and tavern had caught fire. Then, minutes later, the miracle would disappear, and up and down Eighteenth Street the kids who had lined up for blocks were left to wonder if the sun’s sole purpose was to torture them with a paradise they would never reach.

We called this the Revelation. We’d named the event as kids, when Rogelio Ramirez, who grew up with the rest of us on Throop Street, began reading the Bible and reciting from the Book of Revelation as the sun set. He’d stand on the corner stoop of Trebol’s tavern, Bible open in his left hand, drawing exclamation points in the air with his right. “The Woman and the Dragon!” Rogelio would say. “The Fall of Babylon!” Occasionally, the men going into the tavern would stop and listen, as if contemplating the passages Rogelio read, but something in them always snapped, and they’d break into laughter and call Rogelio “The Pope” or “The Saint of Throop Street.” Rogelio never cared. He’d simply raise his voice even higher, bring his arm down even harder. Eventually, the men would retreat into the smoky darkness of Trebol’s, the thick black door sweeping shut behind them. The small diamond of mirrored glass at its center staring down at us as if a horde of curious drunks were peering out from behind it. When the sun dropped below the horizon, Rogelio would snap his Bible shut, turn on his heels, and march back down Throop Street, like a leader into flames.
