Input: Text: i was walking out of one of my morning classes, still not fully woken up and pretty oblivious to my surroundings. my gum had run out of flavor during class so i needed to dispose of it. i exited class and rounded the corner, where i know there is usually a trashcan. i wasn't really paying attention and just tossed it at something that looked like a trashcan out of my peripheral. i kept walking for maybe another 5 steps until i hear "what the fuck asshole." i turned around and realized it was actually just a girl sitting on a bench with her laptop. she got pretty pissed and i tried to apologize, but i just felt like a complete douche. there’s really no way to play off mistaking a girl for a trashcan.

TIFU by throwing my gum on someone thinking they were a trashcan
