Input: Text: well tifu, i've been browsing for a while, blahblahblah, first post ever here, blahblahblah, etc.

my story starts out at my high school. at nighttime our janitors lock the staircases to the hallways to prevent people from roaming too much.

now my school counselor comes up to me during school and asks if i can record for his college talk to the juniors (i'm a senior). so after school, at about 5pm, i go downstairs before the staircases are locked. i go in our media and film class and grab the camera saved for me. after heading back upstairs, i see our janitor locking the door behind me. no biggy.

so i take off my stuff, including my keys and jacket, and set up the camera to record, and it says i have 1h ½ video storage available. that's fine, i thought the meeting wouldn't be too long. man i was wrong.

this meeting didn't end. as the timer on the camera counted down from 5 minutes, i decided i'm going to need another camera. i go into the staircase to go downstairs, and hear a *click*. there's the door.  now i, thinking it a smart move, should go outside and check the other entrances. they're all locked.

i manage to squeeze my way into one of the staircases (a glitch in the matrix). i decided now's the time to call my counselor, still in the meeting, and have him open the door. nope. his phone's off. i proceeded to go outside and check to make sure the cars are still there, and do this every 15 minutes. finally some of the cars start disappearing, so i headed to the front door, and low and behold, there's someone by the door! made it back inside in time to pick up my stuff and leave.

if there's any confusion, just comment below and i'll edit the op. (this was posted from my phone)
