“That is really lovely,” my mom said. I liked that they liked each other. “But isn’t it also that on some fundamental level we find it difficult to understand that other people are human beings in the same way that we are? We idealize them as gods or dismiss them as animals.”

“True. Consciousness makes for poor windows, too. I don’t think I’d ever thought about it quite that way.”

I was sitting back. I was listening. And I was hearing something about her and about windows and mirrors. Chuck Parson was a person. Like me. Margo Roth Spiegelman was a person, too. And I had never quite thought of her that way, not really; it was a failure of all my previous imaginings. All along — not only since she left, but for a decade before — I had been imagining her without listening, without knowing that she made as poor a window as I did. And so I could not imagine her as a person who could feel fear, who could feel isolated in a roomful of people, who could be shy about her record collection because it was too personal to share. Someone who might read travel books to escape having to live in the town that so many people escape to. Someone who — because no one thought she was a person — had no one to really talk to.

And all at once I knew how Margo Roth Spiegelman felt when she wasn’t being Margo Roth Spiegelman: she felt empty. She felt the unscaleable wall surrounding her. I thought of her asleep on the carpet with only that jagged sliver of sky above her. Maybe Margo felt comfortable there because Margo the person lived like that all the time: in an abandoned room with blocked-out windows, the only light pouring in through holes in the roof. Yes. The fundamental mistake I had always made — and that she had, in fairness, always led me to make — was this: Margo was not a miracle. She was not an adventure. She was not a fine and precious thing. She was a girl.

The clock was always punishing, but feeling like I was closer to unraveling the knots made time seem to stop entirely on Tuesday. We’d all decided to go to the minimall right after school, and the waiting was unbearable. When the bell finally rang for the end of English, I raced downstairs and was almost out the door when I realized we couldn’t leave until Ben and Radar finished band practice. I sat down outside the band room and took a personal pizza wrapped in napkins from my backpack, where I’d had it since lunch. I was through the first quarter when Lacey Pemberton sat down next to me. I offered her a piece. She declined.

We talked about Margo, of course. The hole we had in common. “What I need to figure out,” I said, rubbing pizza grease onto my jeans, “is a place. But I don’t even know if I’m close with the pseudovisions. Sometimes I think we’re just entirely off track.”

“Yeah, I don’t know. Honestly, everything else aside, I like finding stuff out about her. I mean, that I didn’t know before. I had no idea who she really was. I honestly never thought of her as anything but my crazy beautiful friend who does all the crazy beautiful things.”

“Right, but she didn’t come up with these things on the fly,” I said. “I mean, all of her adventures had a certain. . I don’t know.”

“Elegance,” Lacey said. “She is the only person I know who’s not, like, grown up who has total elegance.”

“Yeah.”

“So it’s hard to imagine her in some gross unlit dusty room.”

“Yeah,” I said. “With rats.”

Lacey pulled her knees to her chest and assumed the fetal position. “Ick. That’s sonot Margo.”

Somehow Lacey got shotgun, although she was the shortest of us. Ben was driving. I sighed quite loudly as Radar, seated next to me, pulled out his handheld and started working on Omnictionary.

“Just deleting vandalism on the Chuck Norris page,” he said. “For instance, while I do think Chuck Norris specializes in the roundhouse kick, I don’t think it’s accurate to say, ‘Chuck Norris’s tears can cure cancer, but unfortunately he has never cried.’ Anyway, vandalism-deletion only takes like four percent of my brain.”

I understood Radar was trying to make me laugh, but I only wanted to talk about one thing. “I’m not convinced she’s in a pseudovision. Maybe that’s not even what she meant by ‘paper towns,’ you know? There are so many place hints, but nothing specific.”

Radar looked up for a second and then back down at the screen. “Personally, I think she’s far away, doing some ridiculous roadside attraction tour that she wrongly thinks she left enough clues to explain. So I think she’s currently in, like, Omaha, Nebraska, visiting the world’s largest ball of stamps, or in Minnesota checking out the world’s largest ball of twine.”

With a glance into the rearview mirror, Ben said, “So you think that Margo is on a national tour in search of various World’s Largest Balls?” Radar nodded.

“Well,” Ben went on, “someone should just tell her to come on home, because she can find the world’s largest balls right here in Orlando, Florida. They’re located in a special display case known as ‘my scrotum.’”

Radar laughed, and Ben continued. “I mean, seriously. My balls are so big that when you order french fries from McDonald’s, you can choose one of four sizes: small, medium, large, and my balls.”
