Not shocking was the fact that at first, the office was completely distracting. I actually felt a little nauseated, sitting there, a condition exacerbated when I turned on the desk lamp, which had an orange shade and made everything seem even more radioactive. But after a few minutes with the calculator and the checkbook, it all just kind of fell away. I hadn’t realized how much I missed the simplicity of a project of numbers, how things just made sense in sums and division. No emotion, no complications. Just digits on-screen, lining up in perfect sequence.

I was so immersed, in fact, that at first I didn’t even hear the music coming from the store behind me. It was only when it suddenly got very loud, like someone had twisted the volume from the lowest to highest setting, that it broke through the tax forms I was looking at and got my attention.

I looked at the clock – it was 9:01 – then pushed my chair back and eased the door open. Out in the hallway, the music was positively deafening, some disco song with a fast beat, a girl’s voice chanting some lyrics about a summer crush over it. I was wondering if maybe they were having some issue with the stereo system when I saw Esther suddenly go shimmying past the jeans display, her arms waving over her head. She was followed, moments later, by Leah, doing a slow, hip-swiveling move, and then Maggie, bouncing on her tiptoes. It was like a conga line of three, passing quickly, then gone.

I took another step forward, leaning out a bit more into the store. I couldn’t see any customers, although the boardwalk looked crowded, lots of people passing by. I’d just decided to go back to the office and wait for the silence to return when Esther popped up from behind the bathing-suit rack, this time doing a step-slide, step-slide move, her hair swinging out to the side. She reached out a hand to Leah, pulling her into view, then spinning her out and back toward her as they both laughed. Then they split, and Maggie moved in between them, shaking her hips as they circled around her, still dancing.

I didn’t realize I was standing there just staring at them until Esther saw me. ‘Hey,’ she called out. Her cheeks were flushed. ‘It’s the nine o’clock dance. Come on.’

Instinctively, I shook my head. ‘No thanks.’

‘You can’t say no,’ Leah yelled as she grabbed Maggie’s hand, then spun her out and back again. ‘Employee participation is mandatory.’

Then I quit, I thought, but already they were moving on, back to the conga line, this time with Maggie in the lead, bouncing up and down, Esther snapping her fingers behind her. Leah, bringing up the rear, glanced back at me one last time. When I didn’t say or do anything, she just shrugged, following the others as they wound around the displays, and headed toward the door.

I went back to the office, sitting down at the desk. I was sure they thought I was a total stick-in-the-mud, not that I cared. It was just like all the activities I’d walked past at my old schools during lunch – fake sumo wrestling, pie-eating contests, mass games of Twister on the quad – always wondering how, exactly, you did stuff like that. Maybe if you’d done it as a kid, it was all nostalgia, and that was the appeal. But I hadn’t. It was all new to me, and therefore more intimidating than anything else.

I picked up my pen, going back to my 1099s. A moment later, the music stopped, as suddenly as it had begun. Another hour passed, in the silence of numbers, and then there was a tap on the door.

‘Closing time,’ Esther said as she came in behind me, a bank bag in one hand. ‘Can I get in the safe?’

I pushed out my chair, making room as she dropped down to a squat, sticking the key she was holding into the lock. I watched as she put the bag in, then swung the door shut before pushing herself up again.

‘We’ll be out of here in about ten minutes,’ she told me, brushing off her knees. ‘You coming with us, or staying late?’

I wanted to tell her that, to me, after ten wasn’t late. But I knew she wasn’t really looking to make conversation, so I said, ‘I’m almost done.’

‘Cool. Just come out front and we can lock up when we’re all out.’

I nodded. She left the door open behind her, so as I finished up the last few things I had going, I could hear her and Maggie and Leah, out by the register chattering.

‘Where did these Skittles come from?’ Esther asked.

‘Where do you think?’ Leah told her.

‘Really.’ I could tell by her voice, slightly teasing, that Esther was smiling. ‘So, Mags. More candy from Adam, huh?’

Maggie sighed. ‘I told you guys, it means nothing. He’s a store-goer, just like all those boys.’

‘That may be true,’ Leah said, ‘but just because he goes to the store doesn’t mean he has to buy something for you every time.’

‘He doesn’t do it every time,’ Maggie grumbled.

‘Sure seems like it,’ Esther said. ‘And with a store-goer boy, that is the first sign, anyway. It’s how you know.’

‘True,’ Leah agreed.

‘Not true,’ Maggie said. ‘It’s just candy. Stop reading so much into it. You guys are ridiculous.’

I could second that. It amazed me that they’d been together all night, and yet they still, seemingly, had something to talk about. Even if it was, predictably, candy and boys.

When I came out, they were all by the front door, waiting for me. ‘I understand if you don’t want to get involved with him,’ Leah was saying. ‘I mean, he is a high school boy.’
