Input: Text: obligatory: this happened fifteen years ago. i still don't quite understand what happened and i feel terrible to this day.

when i was a kid, my friend karissa's dad was driving her and me somewhere in his small-penis, two-door sports car. where we were headed, i cannot recall. i was sitting shotgun and karissa was behind me. we arrived at our destination and i got out of the car. i pulled the lever to move up the seat to let karissa out of the back. 

she was half way out of the car, i was standing at the door staring right at her and then, compelled from some dark, twisted place usually buried in my subconscious, i slammed the door, hard, right in her face. i slammed it harder than i have ever shut any door before or since. it smacked her in the head with ungodly force and i will never forget her confused look through the greenish-tempered glass as she flew backwards into the car. her dad gave me this perplexed look as he shouted "you were looking right at her!!! you were looking right at her!!!". i just stood there, frozen to the spot, mouth agape trying to understand what i had done as blood began to run steadily down karissa's forehead. she stared back at me with the very same expression. 

i can't remember where we were going, but i remember where we went-- the er to get karissa some face stitches.

TIFU by slamming a car door.
