Theresa tapped her fingers against the aged leather of the steering wheel, mouthing words to the rhythm of an old love song blaring...

I got home from work at six-thirty. Traffic on the beltway had been particularly egregious this evening, but at least it was Friday. I had a pounding headache from dealing with Maryland drivers and I wanted nothing more than to catch up on shows while snuggling on the couch with Jenna, my partner of almost ten years and wife for a few of them.

It was late and more hatchlings had been drawn to this college campus. They could sense the body heat from miles away as it was the closet human establishment to the crash site.
