Input: Text: so i'm still super embarrassed by this. not a long story by the only real fu i've had since discovering this subreddit.

i live in a three floor on campus housing unit. the building holds a couple hundred students, and i live in the third floor with some friends. 

a couple days ago i had a meeting with the rd (office is on the bottom floor of my dorm building) discussing some things, as i was in the meeting my friend (who i live with) texted me asking if after i finish the meeting i would go to the dining hall. so when i finished, i texted him and he said he was on his way down.

here is where the fu happened. i waited at the door to the stairwell and i heard a door open and close from up the stair well and i heard someone coming down the stairs. i thought, "wouldn't it be hilarious if i scared the shit out of him as he came through the door?"

he is in the national guard, and a very built and tough dude. i'm not so much. you see where this is going? you're wrong. 

so i waited, and as soon as the door opened i yelled.

it wasn't my friend. it was a terrified girl. i was so surprised i could barely say anything and she ran away almost crying...

TIFU by scaring the shit out of someone.
