From Michelle Arnold:

As I left a party, I got on the wrong freeway and was immediately lost. I pulled over to the shoulder and called my roadside-assistance provider. She tried to connect me to the California Highway Patrol, but that call never went through. Hearing the panic in my voice, she came up with a plan B: “You’re near this office,” she said. “I’m about to go off shift. Stay put, and I’ll find you.” Ten minutes later, she rolled up. She guided me not only to the right freeway, but all the way to the correct freeway exit. And then, with a wave goodbye, she drove back into the night.
