Seven years driving Route 6 and you start to think you know every mailbox, every loose dog, and every nervous kid on the blacktop. You learn which ones throw their lunchboxes at each other in the back seat and which ones just stare out the side glass until their stop comes up. Katie was a window-starer. She was seven years old, small for her age, and she had this habit of sitting right behind the yellow line like she was trying to disappear.

It started back in October when the leaves were dropping red and yellow all over the ditches. Katie hung back while the other kids scrambled for the stairs, letting the whole bus empty out before she walked slow up to my seat. She asked me, real quiet, if she could tell me something without getting in trouble. I told her she wasn’t going to get in trouble for talking to her driver.

She leaned in close so the seventh graders in the back wouldn’t hear her over the rattle of the old diesel engine. She wanted a way to tell me not to let her off at her stop if things looked bad at her house, but she couldn’t have her mama or anyone else knowing she’d talked to me about it.

I should have called the school office right then and asked for a welfare check. I know that now, looking back on it with nine years of district rules ringing in my ears.

But I was scared of getting it wrong, of some bureaucratic mess, of losing my route over a kid being dramatic or a mother being late. So instead I looked down at her small, sneakers-wearing feet and made a bad bargain with a seven-year-old.

I told her, “Baby, you watch your own porch light. If you don’t want off, you flip that switch twice. I’ll see it. I’ll keep driving.”

She practiced it that very week. I’d pull up to her gravel drive and sit there for ten seconds letting the air brakes hiss, and she’d be standing on the top step flipping that little brass toggle switch up and down. Open steady, all’s fine. Two quick blinks, come back around.

For two months the light stayed solid yellow every single afternoon. I started to tell myself it was just a scared kid’s game, some kind of imaginative streak she picked up from television.

I let my guard down because nothing bad had happened yet, and human beings are terrible at preparing for things they desperately want not to be true.

Then this Tuesday rolled around like any other grey, chilly afternoon in the county. I turned my bus off the highway onto her stretch of gravel, watching the windshield wipers smear a light mist across the glass. And right away my stomach dropped straight through the floorboards.

There was a big black pickup truck parked right in front of Katie’s porch, mud caked up the side panels and an oversized toolbox in the bed. Renae, Katie’s mama, drove a little dented grey hatchback that rattled like a tin can whenever she took it out for groceries. That truck didn’t belong there. It looked heavy and mean parked against the peeling white paint of that old house.

Katie had worked her way up to the front bench seat by then, having earned the right through weeks of quiet good behavior. She went very still beside me, her small hands clutching the strap of her canvas backpack so hard her knuckles looked like peeled garlic.

We rolled to a stop by the mailbox. The porch light flickered once. Then it flickered twice.

My mouth went dry as old dust. I did not pull the lever to open the folding doors.

I kept my hand resting right on top of the black metal handle, feeling the cold air leaking in from the stepwell. I looked back at the three remaining kids chattering in the middle rows, completely unaware of anything except getting home to their cartoons. I tried to keep my voice even so I wouldn’t scare them.

“Miss Katie, why don’t you ride the loop with me one more time today, keep me company,” I said, and I shifted the gear back into first.

I pulled the bus away from that gravel drive before anyone could step off the porch. In the large convex side mirror, I watched the front door of Katie’s house swing open. A big man stepped out onto the wood planks, heavy-shouldered and wearing a faded flannel shirt with the sleeves rolled up. He wasn’t her daddy, and I’d never seen him around those parts before. He just stood there with his hands on his hips, watching my yellow bus crawl down the road until we rounded the bend and the trees hid us.

Katie whispered into the quiet air between us, “That’s Brant. Mama told him not to come anymore.”

I didn’t say anything back to her for a long minute because my throat was too tight to push words past it. I finished the route, dropped the other three kids off at their respective driveways where mothers were waiting with umbrellas and dogs barking at the tires, and I didn’t let Katie off once.

When the bus was finally empty except for the two of us, I drove out past the town limits and pulled the big diesel over on a quiet stretch of gravel by the old grain elevator. I cut the engine, letting the radiator tick and pop as it started to cool down in the damp air. I reached into my pocket and pulled out my phone because I was entirely done being scared of the school district’s rulebook or what some administrator would say about my schedule.

I had two numbers saved that mattered. One was Ms. Adeyemi, the district social worker who actually answered her phone when teachers called, and the other was the county sheriff’s dispatch.

Katie was sitting on the bench seat right behind me, watching my face in the rearview mirror with huge, solemn eyes. She leaned forward and said, “Please don’t get my mama in trouble.”

I turned around in my seat so I could look her straight in the eyes, holding onto the steering wheel with both hands to keep them from shaking. I told her nobody was getting her mama in trouble, that we just needed to make sure everybody was safe for the evening.

Then I dialed the sheriff’s office, and while the phone rang out into the empty cab of the bus, I looked back down the long dirt road toward her house, where that black truck was still sitting in the drive waiting for the porch light to lie.
