He was hurrying south and west of the motel strip, stunned by the heat, hard to see in the jagged morning shadows, his left thumb jammed out urgently, when she pulled over at his side with the wet hiss of wide tires on hot pavement. It was a big white car and the sun on the hood dazzled him. He turned blindly and she buzzed her far window down. Seven forty-two, Friday morning.

"Where to?" she called, like she was a cab driver, not a private citizen.

"Anywhere," he said.

He regretted it, instantly. It was a dumb thing to say, because to have no specific destination usually makes things worse. They think you're some kind of an aimless drifter, which makes them suspicious, and makes them worried they might never get rid of you. Makes them worried you'll want to ride all the way home with them. But this woman just nodded.

"O.K.," she said. "I'm headed down past Pecos."

He paused a beat, surprised. Her head was ducked down, her face tilted up, looking out at him through the window.

"Great," he said.

He stepped off the curb and opened the door and slid inside. The interior was freezing cold. She had the air roaring on maximum and the seat was leather and it felt like a block of ice. She buzzed the window up again with the button on her side as he swung the door shut behind him.

"Thanks," he said. "You don't know how much I appreciate this."

She said nothing. Just made some kind of all-purpose dismissive gesture away from him as she craned to look over her shoulder at the traffic stream behind her. People have their reasons for giving rides, all of them different. Maybe they hitched a lot when they were younger and now they're settled and comfortable they want to put back what they took out. Like a circular thing. Maybe they have charitable natures. Or maybe they're just lonely and want a little conversation.
