“They never knew! I did the whole thing online!” The Schwa told me how he had done it. First he set up a fake website that made it look like he ran a publicity company, then he hired an advertising agency—again online—telling them his company was promoting a new child star, Calvin Schwa. “They never questioned anything, because they got the money up front,” he said. “And money talks.”

I looked again at the billboard. With the streetlights on, and all the billboards lit up, the sky suddenly seemed dark. So did the expressway. In fact, the expressway seemed very dark. Then a nasty realization began to dawn on me with the slow but inescapable pain of a swift kick to Middle Earth, if you know what I mean. Something was very wrong with this picture. Not the Schwa’s massive billboard picture, but the bigger picture. I swallowed hard, and my heart started hip-hopping again. I wondered how long it would take the Schwa to notice. He seemed so thrilled as he stared at his own unavoidable face, I wondered if he ever would. I thought about how you’re not supposed to wake sleepwalkers, and wondered if bursting a friend’s bubble was the same thing. Then I realized that I didn’t want to. Let him have his dream. Let him be like his father just this once, and happily sleepwalk through this.

“It’s getting late—we’d better go,” I told him, trying to lure him away from that window.

“In a few minutes,” he said, still marveling at the billboard. “Do you know how many thousands of people pass this spot every day?”

I tried to tug him away from the window. “Yeah, yeah. Let’s just go!”

“Do you have any idea how many cars are going to drive by and—” That’s where he stopped, and I knew it was all over. His bubble didn’t just burst, it detonated.

“Where . . . are . . . the cars?” He said it slowly. Just like someone who really was waking up out of a dream.

“Forget it, Schwa. Let’s just go.”

I grabbed him and he shook me off. He stuck his whole head so far out of the broken window, I was afraid his throat would get slit on the broken glass.

He looked to the left, looked to the right, then pulled his head back in and looked at me.

“Where are all the cars, Antsy?”

I sighed. “There aren’t any.”

“What do you mean ‘there aren’t any’?”

“The Gowanus Expressway is closed for construction.”

The Schwa gave me an expression so blank, I swear I really could see right through him. “Construction . . .” he echoed.
