We ran through the grey light. The morning had dawned cold, and even at the lakeside the air was pretty dry. Thomas got ahead of me for a couple of steps, looked back, and kicked his heel, flinging sand into my face and eyes. I inhaled some of it, started gasping and choking, but managed to hook my fingers in the back of Thomas's T-shirt. I tugged hard as he stepped, and I outweighed Thomas considerably. He stumbled again, and, choking and gasping, I got ahead of him. I regained my lead and held it.

The last hundred yards were the worst. The cold, dry air and sand burned at my throat, that sharp, painful dryness that only a long run and hard breathing can really do to you. I swerved off the sand toward the parking lot, Thomas's footsteps close behind me.

I beat him back to the SUV by maybe four steps, slapped the back of the vehicle with my hand, then leaned against it, panting heavily. My throat felt like it had been baked in a kiln, and as soon as I could manage it I took the keys out of my black nylon sports pouch. There were several keys on the ring, and I fumbled at them one at a time. After the third wrong guess I had a brief, sharp urge to break the window and grab the bottle of water I'd left sitting in the driver's seat. I managed to force myself to try the keys methodically until I found the right one.

I opened the door, grabbed the bottle, twisted off the cap, and lifted it to ease the parched discomfort in my throat.

I took my first gulp, and the water felt and tasted like it had come from God's own water cooler. It took the harshest edge off the burning thirst, but I needed more to ease the discomfort completely.

Before I could swallow again, Thomas batted the water bottle out of my hand. It arched through the air and landed on the sand, spilling uselessly onto the beach.

I spun on Thomas, staring at him in surprised anger.

He met my gaze with weary grey eyes and said, "It's like that."

I stared at him.

"It's exactly like that." His expression didn't change as he went around and got into the SUV on the passenger side.

I stayed where I was for a moment, trying to ignore my thirst. It was all but impossible to do so. I thought about living with that discomfort and pain hour after hour, day after day, knowing that all I had to do was pick up a vessel filled with what I needed and empty it to make me feel whole. Would I be able to content myself with a quick splash of relief now and then? Would I be able to take enough to keep me alive?
