Past

Day 1:
Crap...what the hell happened? All I saw was a bright light, and BOOM! Everything is gone...everyone is gone...
Wait, there's more survivors...I'll be back soon.

Day 5:
Damn, I lost you for awhile, huh? Being in this crowded building doesn't help. There are only men here, no one knows where the women or children went, it's like they disappeared with the light....
More meteors are coming...what the hell?!

Day 6:
There was screaming...and now there's blood...oh god so much blood! Out of the 100 that were here, only 50 are left. What's happening? The sky is blood red, we're all fighting... I found a picture in my pocket today, I was in it with a woman and two children...
The hell are they??
Maybe tomorrow will bring light to this...

Day 10:
     I found a briefcase today, it was in the car I was near when all this crap happened. It had a gun, a revolver to be exact. None of the men realize this, I hid it in my cot...
If this gets too much...I'm using it...

Day 11:
Okay...I didn't hide the gun as well as I thought, one of my somewhat friends, George I think his name was, made quite a show today. He held my gun to his head, screamed unintelligible words and pulled the trigger...
His damned brains splattered all over the place, on me,
Damn how he got it on me...
Why did I...enjoy it so much?
I'm laughing now at it...

Day 20:
Okay, something fucked up is happening... I went through the suitcase and found another picture of the woman and two kids...
Their throats were slit...
Blood was even on the picture..
What sick fuck would do this...and why am I enjoying this so much?!
I'm fucked up...

Day Revelation:
Remember those kids and woman I was talking about? Yeah...I think I killed them..I had a dream about how I killed them...they didn't struggle...they died peacefully, those children...but the woman, the whore as I remember thinking, she was killed slowly, I remember it...
That damned bitch cheated on me...
Cheated on me with her husband...
Who was she to break off her affection for me...
To make things right for her husband....
Funny...he looked a lot like George...
Too bad I shot him...
I made it look like a suicide...those men will never know...
I will make sure of it
