The Tide Table Test

Thelma had been compiling tide tables at the coastal post office for six years, thirty-two years old and unmarried and mostly content, and in all that time she had never told a single soul about the thing she did in the parking lot after close. It was not a big thing, not really, and that was probably why it had stayed private so long, because it was easy to keep a secret that took up only about four minutes of your evening and required nothing but a streetlight and a little nerve. The streetlight at the edge of the lot was old, the kind the county kept promising to replace, and it had developed a habit of pulsing, going dark for a beat every four seconds and then flaring back amber like it was surprised to be awake. On a normal night a person would call it a nuisance. On Thelma's nights it was a metronome, and she had built an entire quiet ritual around it that she did not have a name for and did not especially want one.

She stepped out at dusk on a Tuesday, the way she did most evenings, with the lobby locked and the mail already sorted and the tide tables for next quarter sitting nearly finished on the back-office desk where she could see them through the glass door. The lot was empty except for her own Corolla and one flicker of another thing, far out at the gravel edge, a truck with its engine running and its headlights on. She noticed it the way you notice a mosquito in the bedroom, first with irritation and then with something warmer underneath, because she had been noticing that same truck for four evenings now, parked in the same far spot, never coming in, never leaving early.

She had recognized the driver on the second evening, when he stepped out to stretch his back, purely out of habit from years of selling postage to everyone in the county, and had not been entirely surprised to find it was Trey, who had been in her community-college cooking class eleven years ago when she was twenty-one and he was twenty-two, back when the instructor paired all the single students up as fake couples for the semester. He had been decent at roux and terrible at small talk, and she had thought about him maybe twice a year since.

She walked to the middle of the lot, right under the light, and stood still.

The pulse washed over her face, amber, then dark, then amber, four seconds apart, and she counted the first one out of habit and let the second one land on her skin like a warm hand. This was the whole point of it, though she would never have phrased it that way to anyone. The light touched her, then took itself away, then touched her again, and somewhere in the first year of this ritual she had realized that what she liked was not the light at all but the rhythm of being seen by something and then not seen, over and over, on a schedule she could trust. It had started as nothing, just a way to breathe after a day of weighing packages for people who complained about stamp prices, and it had turned into the one part of her day that belonged entirely to her.

And now there was a truck, and a man in the truck, and the strange truth was that knowing he was there made the amber feel warmer, not colder.

She felt the flicker of thrill move through her, quick and unmistakable, the same one she had felt on the second evening when she finally understood the truck was not waiting for the mailbox to clear. He was there for this. He was parked a hundred feet out with his lights on as if he had not decided whether he was allowed to be there, and the fact that he kept coming back, night after night, sitting through whatever small show the light put on with her standing under it, did something to the back of her knees that she had not expected and did not plan to apologize for.

On the fourth pulse she moved her hands to the top button of her shirt.

This was new. This was the part the ritual had been circling for weeks without landing on, the way a dog circles a spot before lying down. She wore a plain work shirt, blue, buttoned to the collar because the post office held certain views about collars, and the top button was small and brass and had never meant anything to anyone. She popped it free on the dark beat, so that the light came back up on an open collar and the small triangle of skin below her throat that the county had never been allowed to see. Nothing criminal in it. Nothing anyone could even complain about. But the amber fell on that new sliver of skin and she felt it like a spotlight, and her breath went shallow in a way that made her smile at herself, thirty-two years old, standing in a post office lot getting flustered by a streetlight.

The truck's headlights cut out on the next dark beat.

That was the moment that decided things, though she did not know it yet. Cutting the lights was a commitment, a way of saying I am not pretending to be here for some other reason, and Thelma stood under the pulse with her collar open and understood that she had an audience, a real one, a man who had driven out three nights in a row to watch a woman stand under a broken light and unbutton one button. She should have been embarrassed. She had a whole speech ready in her head about embarrassment, actually, a little internal lecture about dignity and county property and how she was going to march over and tell him to move along. The speech dissolved somewhere between the sixth pulse and the seventh, replaced by a much simpler thought, which was that she wanted to know what he thought he was watching, and the only way to find out was to ask him.

She left the second button alone, barely, and walked across the lot.

The gravel crunched under her post office loafers in a completely unglamorous way, and she was aware of how the whole picture must look from the truck, a stocky woman in a blue work shirt striding out of a pool of amber light like a deputy coming to check on a suspicious vehicle. Trey's window was down already, which she noticed halfway there and which made her feel either better or worse about the whole situation, she could not decide which. He sat with his hands on the wheel, and she could see his face in the dying light, and he did not appear to be a man who had been caught. He appeared to be a man who had been waiting to be caught.

"Evening," she said, leaning her forearms on the window frame, close enough to feel the warmth coming off the dashboard. "You've been out here three nights."

Trey nodded, unhurried. "Four, counting tonight."

"Well, that's honest, anyway." She looked at him properly, at the graying temples and the dental-practice polo and the same awkward way of holding his shoulders he'd had in cooking class when the instructor told them their béchamel had broken. "You want to tell me what you think you're watching out here, Trey?"

He did not flinch at the sound of his own name, which told her he had known she would figure it out eventually. "The light does that thing," he said, gesturing at the streetlight with his chin, "every four seconds, where it goes out and comes back. And you stand under it. And you wait for it. And tonight you unbuttoned your collar on the dark part, so the light came back on you." He paused, and his hands flexed on the wheel once. "I know how it sounds. I wasn't going to say anything. But since you walked over here and asked, I'll tell you plain. I've been coming to watch you watch that light, and I'd have kept coming, and I'm not embarrassed about it, so there's no point pretending otherwise."

Thelma straightened up out of the window frame and stood there while the pulse rolled over both of them, amber, dark, amber, and thought about the fact that she had been seen, actually seen, for the first time in six years of doing this, and that the sky had not fallen.

"Come inside," she said, stepping back from the truck. "It's cold, and I make coffee in the back office like someone who's given up, and I have eight pulses' worth of questions for you."

The coffee was bad, the way office coffee is bad when nobody has replaced the pot in six years, and Trey drank it anyway, standing at the edge of her desk where the tide tables fanned out in neat stacks, each one labeled by month in her careful block letters. Thelma sat on her rolling chair with her mug balanced on her knee and studied him while the space heater ticked away in the corner. He was thirty-three now, eleven years out from the cooking class where they had been paired up as fake couples for a whole semester, and he was the way you remember a good meal you ate once and never found on a menu again. It appeared the roux skill had not translated into anything and the small talk had improved somewhat, because he was managing full sentences now.

"So the ritual," he said, turning his mug a quarter turn on the desk. "The whole thing takes about four minutes. I timed it."

"You timed it."

"Three evenings, yes. Four minutes, give or take. You stand in the middle of the lot, you wait for the pulse, you do one small thing on the dark beat, and then you stand there until the next one." He looked at her over the rim of the mug. "I want to understand it. That's all. I'm not asking you to explain if you don't want to."

Thelma took a sip of her terrible coffee and thought about six years of doing this alone, most evenings at dusk, the lot empty, the amber washing over her in its patient rhythm, the whole private architecture of it that she had never once described out loud to another living soul. And now here was a man who had measured it with a stopwatch from a truck.

"Here's what I'll do," she said, setting the mug down on the desk next to the January table. "Tuesday, next week, same time. I'll do the ritual, but this time I'll do all of it, the whole thing, everything I've never done with anyone watching." She held up
