"Everyone always wants to know how you can tell when it's true love, and the answer is this: when the pain doesn't fade and the scars don't heal, and it's too damned late.
The tears threaten to return, so I willfully banish all thoughts from my head and take a few more deep breaths. I'm suddenly dizzy from the panic attack I've just suffered, and I close my eyes, resting my head against the warm leather of my steering wheel. Loneliness doesn't exist on any single plane of consciousness. It's generally a low throb, barely audible, like the hum of a Mercedes engine in park, but every so often the demands of the highway call for a burst of acceleration, and the hum becomes a thunderous, elemental roar, and once again you're reminded of what this baby's carrying under the hood."
