After David had walked through every room and confirmed that Allison was not in the house, he decided to try and call her cell phone.  First, he picked up his own cell phone and found that he had no signal, which had never happened in his house before.  Then he tried the land line and found that it was dead, as well.  Again, David couldn't think of anything else to do, so he sat down and ate his cereal. 

He once again considered going back to bed, but instead decided to check with the neighbors to see if their power was out.  Going outside, David saw that the sun was beginning to break up the haze and the sky seemed normal to him now.  He wondered if his half-asleep mind had merely tricked him into seeing the odd lighting earlier.  He trudged next door to his neighbor's house (the single mom that looked excellent in her little jogging outfits, not the creepy old man on the other side that sometimes looked at Allison for just a little too long) and knocked on the door.  He waited for twenty seconds and then pushed the doorbell.  Nothing.

David woke up exhausted and disoriented.  The room was dark and it took him a moment to realize that the utter darkness was a result of there being no power.  The LED's on his alarm clock normally would allow him to get his bearings, at least, but the total absence of light furthered his confusion, not to mention the simple fact that he had no idea what time it was. 

He briefly considered the merits of just rolling over and going back to sleep, but the feeling in his bladder told him that the attempt would be useless.  He threw back the covers and swung his legs to the floor.  Reaching to the nightstand, he found the alarm clock and felt for the cord to make sure it was still plugged in.  It was.

Still trying to shake the sleep from his legs, David used the nightstand as a crutch to stand and make his way to the door to the master bathroom.  Through the bathroom was a walk in closet and when he opened the door, he finally could see some light coming from a window in the closet.  The light seemed muted and hazy and David was drawn to the window to see why.  His eyes were still adjusting to the light when he looked out.  The sky seemed to have a peculiar texture to it, like how the world looks right before a big thunderstorm at dusk, but there wasn't a cloud in the sky.  He flipped the light switch in the closet to check the power, but the light didn't come on.
