What is the backstory here? (Details inside)

This morning, about 7:15 am I stopped for gas. On the opposite side of the pump was a woman, mid to late 20’s, crying. She was not sobbing, just standing there, pumping gas into her silver Accord with tears streaming down her face. She was on her way to or from somewhere, neatly dressed in a skirt, blouse and open jacket , low heels, bejeweled with a necklace of colored stones with a matching bracelet. Gold hooped earrings dangled from within her dark, windblown hair. Her makeup was obviously done in front of a mirror and not hurriedly in the car although her eyeliner had run slightly from the tears.
She had that faraway look in her eyes, staring without seeing, her thoughts travelling on their own path. As I stood there wondering if I should ask if she was ok, the pump clicked to a stop and she came back into the world of the mundane. She saw me for the first time and smiled wanly as she slid back in behind the wheel of her car.
She brushed the hair out of her face and looking in the rearview mirror carefully wiped the tears from her cheeks. She looked over at me one more time before she drove off and although she smiled, I could see that the tears had started up again.

I have been imagining the possible scenarios that had occurred prior to our chance meeting and where she went afterward.

What are your thoughts?
