Nowhere To Run

I wake up in our little tree, only to be shaken out, falling onto the hard, cold, concrete, I slowly pick myself up, and dust myself off. "YOU STUPID BITCH! THIS IS ALL YOUR FUCKING FAULT!" She's having another one of her episodes, but this time, she has bloodlust in her eyes..

"S-sis please..." She picks up a large piece of the concrete, and lunges it at me, hitting me in the stomach, causing me to cough up a bit of blood. "SIS? NO! FUCK OFF WITH THAT SHIT! I WANT TO DISOWN YOU SO​ BAD RIGHT NOW." She tossed more pebbles at me, I stand back up, and start to run.

I have no idea why I'm running.. I want to die anyways...

But not like this.

I trip, and my sister manages to catch up a little, but she can't catch up fully before I can get back to my feet and start running again.

~??? PoV~

Such a serene day, nice for a little saunter in this horrid neighborhood. I light a cigarette, and sit on the curb, watching as I exhale large puffs of smoke.

Shortly after a few cars pass, I've finished the 'filth' as some call it, and put it out, crushing it under my boot. I stretch a bit, before walking on.

A short time after I start walking, I get bumped by something very tiny, frail. I look down, and see a very dazed, little girl, being chased by an older one.

"I've got you now, 'little sister...' You should be fucking GLAD your dying for EVERYTHING YOU DID!"

This girl was about as tall as me, only a few inches shorter. I scooped up the smaller one, and gave the older one a death glare.

"Sweetness, whatever may be the matter, what harm did this sweetheart do to you?"

"She's the reason we're sleeping in a FUCKING TREE EVERY NIGHT!" She's in a full rage..."Don't fucking call me 'Sweetness' either, dickface." That was it, I went right up to her and backhanded her, there was no reason for her to be rude to me. She started bleeding a small bit. As I was distracting her I carefully set the small one down, so she could scurry off, and so she did, quite quickly as well. The raging one started throwing small pebbles at me, one at a time I sighed, and walked past her, slightly brushing her shoulder. I lit another cigarette, and put my hood up. She realized the smaller one had left already, and went the opposite direction of which the smaller one scampered. This made me chuckle slightly.

After I had been walking a while, I heard a scream. I heard plenty of screams in this neighborhood, and never bothered to even look, but this one was different. I quickly ran to the area. The girl from before, she was curled up in a ball -quite bloodied as well, coughing up large bits of blood, which was falling from her head, as well as the rest of her body, her clothes were all ripped up as well, two guys, one with a knife, the other with a gun, both towering over her, cornering her in this small alley. I dashed up to the guy with the gun, grabbed it, and shot, but missed the shot into his heart, instead it hit him in the stomach, which works for me. Then, the guy with the knife tackled me. "Bad idea, pretty boy." He hissed, I threw him off into a wall, and shot him straight in the neck. Not what I was aiming for, but I was shaking a lot, during both shots, so I guess it's fine. I dropped the gun, and walked away.

She didn't even give a thanks, how rude.

I walked past a couple corners, until I got a sudden sinking pain in my stomach... My.. gut told me to go back, which I did, going back to the corner I was stepping in something wet, why was it wet? It hadn't rained at all that day, it had just started raining as these questions, thoughts ran through my mind. I looked down.. and.. I saw a pool of blood, and a small body laying in it.
