The nearest tire store is a mile away. I do not know how long it will take me to roll the flat tire — longer than it would one with air in it, I guess. But this is the only thing I can think of. They would not let me on the transit with a tire, even if it went the right direction.

The tire store stays open until nine. If I work my two extra hours tonight and can get home by eight, then surely I can get that tire to the store before they close. Tomorrow if I leave work on time, I might be able to do two more.

I am home by 7:43. I unlock the trunk of my car and wrestle out the spare. I learned to change a tire in my driving class, but I have not changed a tire since. It is simple in theory, but it takes longer than I want. The jack is hard to position, and the car doesn’t go up very fast. The front end sags down onto the wheels; the flat tires make a dull squnch as the tread rubs on itself. I am breathless and sweating a lot when I finally get the wheel off and the spare positioned on it. There is something about the order in which you are supposed to tighten the lug nuts, but I do not remember it exactly. Ms. Melton said it was important to do it right. It is after eight now and dark around the edges of the lights.

“Hey-!”

I jerk upright. I do not recognize the voice at first or the dark bulky figure rushing at me. It slows.

“Oh — it’s you, Lou. I thought maybe it was the vandal, come to do more mischief. What’d you do, buy a new set of wheels?”

It’s Danny. I feel my knees sag with relief. “No. It is the spare. I will put the spare on, then take the tire to the tire store and have them put on another, and then when I come back I can change that for a bad one. Tomorrow I can do another.”

“You — but you could have called someone to come do all four for you. Why are you doing it the hard way?”

“They could not do it until tomorrow or the next day, they said. One place told me to buy a set of tires on rims and change them myself if I wanted it done faster. So I thought about it. I remembered my spare. I thought how to do it myself and save money and time and decided to start when I got home — “

“You just got home?”

“I was late to work this morning. I worked late today to make up for it. Mr. Crenshaw was very angry.”

“Yes, but — it’s still going to take you several days. Anyway, the store closes in less than an hour. Were you going to take a cab or something?”

“I will roll it,” I say. The wheel with its saggy flat tire mocks me; it was hard enough to roll to one side. When we changed a tire in driving class, the tire had air in it.

“On foot?” Danny shakes his head. “You’ll never make it, buddy. Better put it in my car and I’ll run you over. Too bad we can’t take two of them… Or, actually, we can.”

“I do not have two spares,” I say.

“You can use mine,” he says. “We have the same wheel size.” I did not know this. We do not have the same make and model of car, and not all have the same size. How would he know? “You do remember to tighten the ones across from each other — partway — then the others, then tighten the rest of the way in opposites, right? You keep your car so carefully, you may’ve never needed to know that.”

I bend to tighten the lug nuts. With his words, I remember exactly what Ms. Melton said. It is a pattern, an easy pattern. I like patterns with symmetry. By the time I have finished, Danny is back with his spare, glancing at his watch.

“We’re going to have to hurry,” he says. “Do you mind if I do the next one? I’m used to it—”

“I do not mind,” I say. I am not telling the whole truth. If he is right that I can take two tires in tonight, then that is a big help, but he is pushing into my life, rushing me, making me feel slow and stupid. I do mind that. Yet he is acting like a friend, being helpful. It is important to be grateful for help.

At 8:21, both spares are on the back of my car; it looks funny with flat tires in front and full tires behind. Both slashed tires we took off the back of my car are in the trunk of Danny’s car, and I am sitting beside him. Again he turns on the sound system and rattling booms shake my body. I want to jump out of there; it is too much sound and the wrong sound. He talks over the sound, but I cannot understand him; the sound and his voice clash.

When we get to the tire store, I help him lug the flat tires on their wheels into the store. The clerk looks at me with almost no expression. Before I can even explain what I want, he is shaking his head.

“It’s too late,” he says. “We can’t change out tires now.”

“You are open until nine,” I say.

“The desk, yes. But we don’t put tires on this late.” He glances at the door to the shop, where a lanky man in dark-blue pants and a tan shirt with a patch on it is leaning on the frame, wiping his hands on a red rag.

“But I could not get here earlier,” I say. “And you are open until nine.”

“Look, mister,” the clerk says. One side of his mouth has lifted, but it is not a smile or even half a smile. “I told you — you’re too late. Even if we would put tires on now, it’d keep us after nine. I’ll bet you don’t stay late just to finish a job some idiot dumped on you at the last minute.”

I open my mouth to say that I do stay late, I stayed late today, and that is why I’m late here, but Danny has moved forward. The man at the desk suddenly stands taller and looks alarmed. But Danny is looking at the man by the door.

“Hello, Fred,” he says, in a happy voice, as if he had just met a friend. But under that is another voice. “How’s it going these days?”

“Ah… fine, Mr. Bryce. Staying clean.”

He does not look clean. He has black marks on his hands and dirty fingernails. His pants and shirt have black marks, too.

“That’s good, Fred. Look — my friend here had his car vandalized last night. Had to work late because he was late to work this morning. I was really hoping you could help him out.”

The man by the door looks at the man behind the desk. Their eyebrows go up and down at each other. The man behind the desk shrugs. “You’ll have to close,” he said. Then to me, “I suppose you know what kind of tire you want?”

I do know. I bought tires here only a few months ago, so I know what to say. He writes down the numbers and type and hands it to the other man — Fred — who nods and comes forward to take the wheels from me.

It is 9:07 when Danny and I leave with the two whole tires. Fred rolls them out to Danny’s car and slings them into the trunk. I am very tired. I do not know why Danny is helping me. I do not like the thought of his spare on my car; it feels wrong, like a lump of fish in a beef stew. When we get back to the apartment house parking lot, he helps me put the two good new tires on the front wheels of my car and the slashed tires from the front into my trunk. It is only then that I realize this means I can drive to work in the morning and at noon I can replace both slashed tires.

“Thank you,” I say. “I can drive now.”

“That you can,” Danny says. He smiles, and it is a real smile. “And I have a suggestion: move your car tonight. Just in case that vandal comes back. Put it over there, toward the back. I’ll put an alarm call on it; if anyone touches it I’ll hear the alarm.”

“That is a good idea,” I say. I am so tired it is very hard to say this.

“For nada,” Danny says. He waves and goes into the building.

I get into my car. It smells a little musty, but the seat feels right. I am shaking. I turn on the engine and then the music — the real music — and slowly back out, turn the wheel, and edge past the other cars to the slot Danny suggested. It is next to his car.

It is hard to go to sleep even though — or maybe because — I am so tired. My back and legs ache. I keep thinking I hear things and jerk awake. I turn on my music, Bach again, and finally drift to sleep on that gentle tide.
