This is a 3 part story based on the song "pumped up kicks" by foster the people. Also a bit of back story scootaloo is about 16 and in the beginning she is at the south part of town which is basically like detroit

/scootaloo pov/
I was walking home from school when it started to rain. I quickly ran into a nearby abandoned house with the door broken down shielding my papers with a hoof to prevent them from getting wet. As i got in the house I checked to see if my drawings had gotten wet luckily they where fine. I sat down I the corner looking over my homework when I heard a noise coming from the next room "crap" i thought grabbing the pocket knife out of my bag.

(Don't ask me how the pocket knife thing works. Just use your imagination)

"Blank flank" I heard diamond tiara behind me as I was walking away from the school "what do you want" I said angrily I had a really bad day and I knew she could tell "well I was thinking about all these years have gone by and you still don't have a cutie mark" she said smugly "listen here sparkly hat im not I the mood so piss off" I said getting angry at her "ha I don't have to listen to you the fact that you still don't have a cutie mark means you failed at life and you should just end yourself so I don't need to look at your blank flank anymore" she said leaving herself open to a counter attack "are you implying that you look at my ass? cause that's kinda gross" I said winning the argument as she mumbled "whatever" and walked away

/back to the present/
Then I saw a shadowy figure walk over to me and as I pointed the knife at him he said said "don't worry I'm not going to rape you I'm not into filly's" I lowered the knife but I was still cautious as he sat down in the opposite corner of the room "so do you want some booze?" He asked rolling a bottle towards me "whatever" I said taking a drink. even if I was kidnapped and sold into slavery it wouldn't be as shitty as my life is now.

But as I drank we started to talk about life and crap like that and that must have been some strong stuff cause we where talking for an hour about how hard life was and how one would get out of it and "go out with a bang" as they say and so it was then and there a random hobo convinced me to shoot up my school and he would give me a weapon to do it with.
