“It’s—”

“You hate it, don’t you,” she decided, before I could even finish. “You think it’s tacky and derivative.”

“It’s not,” I said quickly. “It’s beautiful. Really striking.”

“Yeah?” She turned to the mirror, reaching up to touch the key, running her finger over it. “It kind of is, isn’t it? Unique, at any rate. You think they’ll sell?”

“You made more?”

She nodded, reaching into the box again. As she laid more bags out on the counter, I counted at least twenty, none of them the same: some keys were smaller, some bigger, some plain, others covered in gemstones. “I got inspired, ” she explained as I examined them one by one. “It was kind of manic, actually.”

“You should definitely put them out,” I told her. “Like, right now.”

In record time, we’d slapped on price tags and organized a display. I was just putting the last necklace on the rack when the clock hit six and the doors opened. At first, the sound was distant, but then, like a wave, it got louder and louder as people spilled into sight, filling the long, wide corridor between us. “It’s on,” Harriet said. “Here we go.”

We sold the first key necklace twenty minutes later, the second, a half hour after that. If I hadn’t been there to see it myself, I never would have believed it, but every single customer who came by paused to look at them. Not everyone bought, but clearly they drew people’s attention. Over and over again.

The day passed in a blur of people, noise, and the Christmas music overhead, which I only heard in bits and pieces, whenever the din briefly died down. Harriet kept drinking coffee, the key necklaces kept selling, and my feet began to ache, my voice getting hoarse from talking. The zinc lozenges Reggie offered up around one o’clock helped, but not much.

Still, I was grateful for the day and the chaos, if only because it kept my mind off what had happened the day before with Nate. All that evening, after I’d taken the pies back and watched them get devoured, then helped Cora load the dishwasher before collapsing onto my bed, I’d kept going over and over it in my head. It was all so unsettling: not only what I’d seen and heard, but how I’d responded afterward.

I never would have thought of myself as someone who would want to help or save anybody. In fact, this was the one thing that bugged me so much about Nate in the first place. And yet, I was surprised, even disappointed, that at that crucial moment—You understand, right?—I’d been so quick to step back and let the issue drop, when, as his friend, I should have come closer. It wasn’t just unsettling, even. It was shameful.

At three o’clock, the crowds were still thick, and despite the lozenges, I’d almost totally lost my voice. “Go,” Harriet said, taking a sip of her umpteenth coffee. “You’ve done more than enough for one day.”

“Are you sure?” I asked.

“Yes,” she replied, smiling at a young woman in a long red coat who was buying one of the last key necklaces. She handed over the bag, then watched the woman disappear into the crowd. “That’s fifteen we’ve sold today,” she said, shaking her head. “Can you even believe it? I’m going to have to go home and stay up all night making more. Not that I’m complaining, of course.”

“I told you,” I said. “They’re beautiful.”

“Well, I have you to thank for them. Yours was the inspiration.” She picked up one trimmed with green stones. “In fact, you should take one. It’s the least I can do.”

“Oh, no. You don’t have to.”

“I want to.” She gestured at the rack. “Or I can make you one special, if you prefer.”

I looked at them, then down at my own necklace. “May-be later,” I said. “I’m good for now.”

Outside, the air was crisp, cool, and as I headed toward the greenway and home, I reached up, running my hand over my own necklace. The truth was, lately I’d been thinking about taking it off. It seemed kind of ridiculous to be carrying around a key to a house that was no longer mine. And anyway, it wasn’t like I could go back, even if I wanted to. More than once, I’d even gone so far as to reach up to undo the clasp before stopping myself.

On that first night, when Nate and I had met, he had asked me, What’s it to? and I’d told him, nothing. In truth, though, then and now, the key wasn’t just to that lock at the yellow house. It was to me, and the life I’d had before. Maybe I’d even begun to forget it a bit over the last few weeks, and this was why it was easier to imagine myself without it. But now, after what had happened the night before, I was thinking maybe having a reminder wasn’t such a bad idea. So for now, it would stay where it was.

After everything that had happened on Thanksgiving, I’d thought things might be a little awkward for the ride on the first day back at school. And they were. Just not in the way I was expecting.

“Hey,” Nate said as I slid into the front seat. “How’s it going? ”

He was smiling, looking the same as always. Like nothing out of the ordinary had happened. But then to him, I supposed that it hadn’t. “Good,” I said, fastening my seat belt. “You?”

“Miserable,” he announced cheerfully. “I’ve got two papers and a presentation due today. I was up until two last night.”

“Really,” I said, although actually, I knew this, as I’d been awake until about the same time, and I could see the lights from his room—two small squares, off to the right—breaking up the dark that stretched between our two houses. “I’ve got a calculus test that I have to pass. Which means, almost certainly, that I won’t.”
