Input: Text: so, i'm going to start this story by setting the scene. this happened when i was in 9th grade, the year before i entered high school. the junior school where i went was a shitty place. a dark-gray building that looked and felt like a prison, surrounded by a 5 ft. wall with fences, so not an educative place to spend your childhood.
the school was downtown, but was never a crowded place. as we were about to leave for high school, after we finished our finals, me and my friends went out one night. spent some time circulating around and when it was about 11pm, someone brought up the idea of breaking into our class and setting some funny traps there, just so tomorrow we all could have a little laugh. obviously, this idea builds up quickly and we plotted the diabolic plan to infiltrate deep into enemy territory in an undercover secret operation. i thought what could go wrong, we didn't have any bad intentions and beside that we planned everything. so as we approach the school from the back and scouted the frontward and climbed the fence easily.
our classroom was located on the first floor somehow close to the fence. so i climb up the window and then i unlock the window through an air ventilation smaller window. and here we are. in the classroom. and by all means we started to smear the class in which we busted our ass all day for 4 years. even though we meant no harm we could guard from ourselves.  we were turning all the desks upside down writing things on the blackboard and throwing chairs all over the place. the idea of setting the place on fire was floating around. what started as a joke turned into a payback and we lost control of ourselves and let the anger consume us. we managed to wreck the class more than an irritated rhino and a hurricane combined. when we let it all out and felt happy for communicating our emotions we decide to leave. since the year was practically over i decide to take a trophy, the mighty blackboard eraser. i grab it and look outside of the window. two shadows were closing in on us, when i suddenly hit me, oh shit i forgot that our school was guarded. now the shit really hit the fan. i shouted to my friends “run” and my best friend followed me down the window. the 3rd dude with us was caught up in surprise. and was left behind. so when we was near the wall he hadn’t left the classroom yet. when i was looking at that wall i realized that it was taller on the inside. with absolutely no experience whatsoever on parkour i tried to do what ezio auditore and prince of persia would do. so i quickly found myself over the fence. i look on my side and see my friend do the same thing. when we meet on top of that fence, 11 ft. above the ground he gave me this look: “now what?”
i notice a light pool and jump to grab it then slide down it just like a brave firefighter. as i was doing so my friend jumps and lands on top of a car. along with the terror caused by the guards, on top of everything a car alarm that was waking the entire neighborhood. then from behind the wall still inside the school looking at us weirdly and with a faint voice said how did you do that? with his "last breath" he waved at us and run in a different direction to find another exit. hoping that he'll find an exit the guard cornered him and he vanished from our sight. we left with a broken heart. half way home we decided to turn back for him. and there he was cleaning the classroom with the guards. we couldn’t go in and confess. anyway tomorrow when we went to school scared but proud to know that our friend didn’t sold us out. i didn’t like the dude a lot but with this he gained a few respect.  but we still came up and admitted cooperating in the crime just because we didn’t want to leave our friend alone. so 48 hours of community service and a suspension. 
we were lucky they didn’t raise charges. but everybody learned about our brave stunt and “a group of unidentified persons” managed to break in and hide spoiled fishes everywhere. 

p.s i still have the blackboard eraser.
