I returned to the counter with a container about a third of the size of the giant one to find Frank and the guy both leaning over the counter, the newspaper between them.

“ Renaissance,” Frank said, tapping his finger on the newspaper, and I somehow wasn’t surprised at all that Frank Porter was now doing the word search with the mini-mart employee. The guy leaned closer, then nodded and circled the word.

“Backward,” the guy said, shaking his head. “They always try and get you that way.”

“Is that it?” Frank asked, looking down at the paper. “Any left?”

The guy must have noticed me then, as he straightened up and reached for the container, scanning it and giving it back to me. “And the rest on pump four?” I asked, handing him my twenty.

“Nicely done,” Frank said. He nodded down at the search, which was now just a collection of pencil circles, the list of words crossed out, and the few lone letters that didn’t fit in anywhere. “Emily, check it out.”

“Oh,” I said, not really sure what to say about this, since I’d never before been in the position to need to compliment someone’s word search. What was I supposed to say? That it looked really thorough?

But before I needed to decide this, Frank was already moving on, plucking my receipt from the counter and starting to fold it absentmindedly. “You ever do Sudoku?” he asked.

“Nah,” the guy said, tucking the pencil behind his ear. “Not my scene.”

“You have to try it,” Frank enthused as I turned to leave, suddenly feeling like I was in the way. “Once you get the hang of it, it’s addictive. Oh, man. You have no idea.”

I heard the guy laugh before the door closed, and I walked over to the pump. I tried to concentrate on fitting the nozzle into the container, and then not spilling the gas everywhere as it started to fill up, but really I was trying not to think about how acutely aware I was that there were two types of people—the type who could talk to anyone and make friends with them, and the type who spent parties hiding and sitting against trees.

“Hey.” I looked up and saw Frank coming to stand next to me. “You okay? I was going to help.”

“I think I have it,” I said. The numbers had started to slow down, and when they stopped, I put the nozzle away, firmly closed the container, and then bent down to lift it—but it didn’t budge.

“Let me get that,” Frank said, bending down as well to grab one side of it. We hoisted it up together, and only then did it occur to me that I could have filled up the container in the truck bed, and made things easier for us. It was just one more thing that had gone wrong tonight, and I added it to the list. “James said we should keep it in the back,” he said as we placed the container into the truck bed. “And even after it’s empty, you should keep the container in your trunk unless you want your car to smell like a filling station.”

“James?” I asked as I walked around the back to the passenger side. I hadn’t noticed a name tag, but maybe Frank had, or maybe they’d just bonded while doing the word search.

“Yeah,” Frank said, nodding toward the guy inside the store, who waved at us. “Nice guy. I think he’s going to give Sudoku a try.”

We got into the truck, and Frank started the engine and dropped a piece of paper into the cupholder with the origami frog—which was when I noticed that what had been my receipt was now folded into a crane. I wanted to ask him about it, but instead, I just put on my seat belt and looked out the window. If Sloane had been there, sitting next to me, I could have gotten her to ask with one look. She would have done it, too. She had never, in the two years I’d known her, backed down from any kind of challenge.

We were halfway back to the Orchard before I broke the silence and spoke up. Our interaction was coming to an end; I could almost see it shimmering in the distance like the finish line at the end of one of my long cross-country races. “Thank you again,” I finally said after silently trying out a few different versions of this. “I really appreciate it. I swear, I’ve never run out of gas before.”

“And I bet you won’t again,” Frank said. He nodded toward his dashboard, which was lit up like a spaceship, bathing his whole side of the car in a cool blue light. “Mine starts flashing and beeping at me if I get below a quarter of a tank, so I’ll usually fill up immediately just to get it to stop.”

“The gauge on my car is broken,” I explained. Normally I wouldn’t have shared this, but I didn’t want Frank Porter to think I was some kind of airhead, in addition to being the sister of a preadolescent adrenaline junkie. “So I just try and be aware of how much I’ve driven.”

Frank glanced over at me, eyebrows raised. “I’m surprised you haven’t run out before now.”

“No, I’m usually really careful,” I said. “But this week . . .” My voice trailed off when I realized I wasn’t about to tell Frank these kinds of details about my life: Sloane vanishing, me driving all over town looking for her, the list. “It’s just been a little crazy,” I finally supplied.

He nodded as he made the turn back into the Orchard. It looked like, while we’d been gone, the evening had started to wind down—there were only a handful of cars still parked there. Frank pulled up next to my car, and even though I’d just been expecting he would drop me off, he helped me lift the container down and then held it steady while I filled up. I dropped the empty container off in the trunk, and when I walked back to the driver’s side, I saw that Frank was reading the bumper stickers that covered the left side. He looked at me, and I could see the question in his eyes, but I looked away as I got behind the wheel and crossed my fingers. I turned the key, and after a moment of sputtering, the car came to life again.

“Working?” Frank asked, leaning in my window a little.

“Working,” I said. I tapped on the gauge. “But don’t look at this. It’s always stuck on half empty.”

Frank leaned closer, contemplating it. “I would say it’s half full.” He smiled at me, and a moment later, I got the joke. But rather than laughing, or saying something in return, I just gave him a tight smile and stared ahead at the steering wheel. Frank turned to head back to his truck, and I suddenly wondered if this had been incredibly rude.

“But seriously,” I said, leaning out the window a little, “thank you. Let me know if there’s anything I can do to pay you back.”

He nodded and held up a hand in a wave as he turned his truck around to leave. But then he stopped and leaned across his truck to look down at me. “Actually,” he said through the open window. “There is something. Can you teach me to run?”

This was so not even close to anything I’d expected him to say that I wasn’t sure how to react at first. This might have been apparent in my expression, because Frank went on quickly. “I mean, I know how to run. I just want to get better at it, maybe train for a 10K or something. You’re on the cross-country team, right?”

I nodded at that, trying to disguise my shock that Frank had any idea what I’d been involved in at school—or, honestly, that he knew anything about me at all. And after I’d started missing practices and meets regularly this past spring, I wasn’t sure that I would still be on the team come fall. But I didn’t think that he needed to know any of that. “Sure,” I said, easily. I was pretty certain that this wouldn’t come to anything, that he would forget he’d asked me, and the next time I saw Frank Porter, it would be at the first day of school in September, when he would be welcoming us all as the senior class president. He had probably only asked so that I wouldn’t feel like I owed him anything. “Anytime.”

“Great,” Frank said. He gave me a smile, then pulled forward, signaling as he turned to leave, even though there was no reason for it. I watched his brake lights until they faded from view, then I turned on my iPod, connected to the ancient stereo via a line in, put my car in gear, and headed for home, ready to put this entire night behind me.
