Mother's Day is the second Sunday in May, and in Baytown the second Sunday in May is a workday for a good many of the mothers. The hospital on Garth Road does not close. The plants on the channel do not close. The kitchen at the restaurant where the rest of the town goes for brunch does not close, and neither does the daycare that watches the cook's kids while she works it. There is a card and a bunch of flowers from the grocery store waiting on the counter, and the woman they are for is on a unit somewhere, or on a floor somewhere, watching numbers, and will get to them tonight.
This is a description, not a complaint. The town is honest about what it runs on, and one of the things it runs on is this.
Let me describe a few of them. None of them is a real person. All of them are people you know.
There is the one on the twelve-hour shift at the hospital, on the floor where the babies come. Houston Methodist Baytown, at 4401 Garth Road, has the only labor-and-delivery unit in town, which means that if you were born in a hospital in this town, you were born under her watch or under the watch of somebody who did her job before her. On Mother's Day the unit is what it is every day: a place where women arrive at all hours and leave a day or two later with a person who did not exist before. The work is mostly waiting and watching, a strip of paper crawling out of a monitor with two lines on it, the contractions and the child's heart, and a nurse who has learned to read the shape of the second one the way an operator reads a trend on a screen. The nurse's own children are at her mother's house. She will see them at eight, after the handoff, if nobody goes into labor at 6:45.
The one on the tower has been an operator for a decade, and she rotates, which means that the calendar in her kitchen has the days colored in and the second Sunday of May is a night. She will sleep through the morning with the blackout curtains pulled, because the body sets its clock by light and the only way to work nights for ten years is to lie to it carefully, and then get up at three, eat with the kids, open the card, and be through the gate before the light goes. From the top of the unit she can see the whole town, the bay flat and gray, the bridge lit up, the flares on the other plants like candles set out on a long table. She will spend the night watching a screen full of pressures and temperatures and listening for the one sound that is wrong. Nothing will go wrong. That is the job: to be there so that nothing goes wrong, twelve hours at a time, and then drive home while the town is waking up and be asleep before the kids get on the bus.
The teacher has the day off, technically, because the school is closed on Sunday. She is at the kitchen table with a stack of something to grade and a phone that will buzz all afternoon with the families of the kids she teaches, because in this town a teacher is on call the way a nurse is, only without the badge. Graduation is in a few weeks. She has thirty seniors who need something from her before then and about half of them will not ask until the last day.
The cook, since she was mentioned, has been on her feet since five, and the brunch crowd is the biggest of the year, and half of the tables have a mother at them who is being taken out, and the woman carrying the plates to those tables will not be taken out anywhere. The daycare closes at six. She will make it with ten minutes to spare, the way she does.
And there is the one who does not have a badge or a lanyard or a floor, who has kept a house running for thirty years around somebody else's rotating schedule. This is the one the town talks about least and depends on most. Her husband worked nights for two decades and then days and then nights again, and every one of those changes ran through her: the meals shifted, the noise in the house shifted, the kids learned to be quiet in the afternoon and loud in the morning, then the reverse. When the turnaround came and he worked seven twelves for six weeks, she worked seven twelves too, on a unit nobody inspected. There is no shift log for it. There is a house that stayed standing.
The town describes the plants on the channel as a continuous process. It is a technical term and a precise one. The other kind of process is a batch: you put the ingredients in, run it, take the product out, clean the vessel, start again. A cake is a batch. A refinery is not a cake. It is a river with people standing in it. Feed goes in one end and product comes out the other without a pause, on Christmas and in a hurricane and at three in the morning on a Tuesday. It has to be staffed every hour. It has to be watched every hour. You cannot shut it down for a holiday, because shutting a plant down and starting it back up are the two most dangerous things you can do to it; the incidents the whole industry studies, the ones with names, cluster at those two moments. The whole design of a refinery, and the whole schedule of the people who run it, comes from that one fact.
But the plants are not the town's first continuous process. They are its second. The first one has been running in every kitchen on every street since before there was a refinery to name it after, and it is the same thing: feed in, product out, no pause, watched every hour, staffed on the holiday, most dangerous when it stops. A child does not stop needing at midnight. A house does not stop needing on a Sunday. The women in this essay are operators of the oldest unit in town, and the unit has never had a turnaround.
The plants on the channel put out energy in the sense you can measure, in barrels and megawatts, and the town is proud of that, and should be. But the town runs on another kind, one with no unit on any gauge, which is somebody being there. A house asleep at two in the morning with one person still awake in it, listening, is running on it. A hospital floor at 6:45 a.m. with one nurse deciding whether to hand off or stay is running on it. Nobody has found a way to put it in a tank, and the plants would stop without it in about a shift.
A control loop, the thing that actually runs a unit, has three parts: something that measures, something that compares the measurement to where it ought to be, and something that acts on the difference. The lesson the industry learned over a century, and paid for, is that the loop should act on small differences early rather than large ones late, and that a good loop is invisible. Nothing downstream ever finds out how close it came. The operator on the tower is watching a system that would drift if she stopped watching, and correcting it before it drifts far. That is what a control room does. It is also what a mother does at a kitchen table at nine at night, going over the week: who needs a ride, who has a fever coming on, whose grades are sliding, what the bank balance is doing. Pressure, temperature, flow. Nothing so dramatic as an emergency. Just the constant small corrections that keep a process inside its limits, hour after hour, so that the people downstream never learn how close it came.
The universe took nearly fourteen billion years to produce something that could look at a sleeping child and decide to stay awake a while longer to be sure. Whatever else that is, it is matter keeping watch over matter, and the person who packs a lunch at 5 a.m. is doing it as surely as the operator on the tower or the scientist at a bench, and with less equipment.
So the card on the counter is right, and so are the flowers, and so is the brunch for the ones who get to go. The town should say the words. But the truest thing it says on the second Sunday in May is the schedule on the kitchen wall with the days colored in, and the house that is quiet in the afternoon because somebody is sleeping off a night, and the floor at the hospital where the lights do not go off, and the woman who will not open the envelope until eight o'clock tonight, and will not mind.
At the top of the unit, a little after dusk, she checks the screen and then looks up. The bay has gone from gray to black. The bridge is a string of lights. Down in the town, in a kitchen she cannot see from here, her mother is putting her children to bed, and the process is running, and nothing is wrong.
