Another breathtaking sunset in the Arizona desert behind you... Your eyes scan the darkening eastern horizon keenly as you drive on this endless stretch of asphalt. Unbelievably, you see the slight figure of a girl beside the road, arm out, hitchhiking, her face and bedraggled features illuminated by the sinking sun. Out here in the middle of absolutely nowhere.
She looks miserably angry and alone, with an edge that gives you pause as you decide whether or not to stop and see what's up... do you stop? Do you keep going and forget about her?
As you slow to a roll and stop, rolling your window down. She looks around warily, looking for another car perhaps, studying you and your vehicle... she stays back from the window but leans down a bit to peer inside.
Hey... I'm heading east. I don't have anything really but I can do work. If you need help with something...
Her tone is grim and cold, her face sullen and set. Clearly not her first ask for a ride... a well-rehearsed script. Her eyes are steely fixed, revealing nothing. She's behind an emotional wall. A big one.
