Dan heard the cell phone alarm; he swiped the red ‘X’ on the phone screen up to end the din. He sat up in the bed for a few moments. One beat, two beats. The cold, from the other side of the wall, hit him in the chest this time. He struggled to get the wet shirt off, as it dried, fresh with the sweat of last night’s sleep, restless, chopped-up dreams, after lying in bed for hours, unable to capture a minute of rest.

He put on his workout clothes, for his morning run, and routine at the local gym. It was his winter gear, the close-fitting, heat-insulating, pants and shirt, the wool cap. Ankle hurt, knee ached, elbow still swollen; he ignored all these complaints. He packed his bag swiftly, toiletries for the showers, clothes for work. Brushed his teeth, with the electric brush. Struggled to zip up the bag. Out the door. Check for keys. Make sure he didn’t leave the gas on.

Outside there was a blood-red, maroon shadow on the moon: a lunar eclipse. Dan stopped and took a cellphone picture. His chest swelled; today was the day to ask for a raise.
