Input: Text: didn't happen today, but happened two weeks ago.

there was this awesome guy at my work and he was the first person i really befriended at work.

one day he just disappeared. it had me really confused, he vaporized off the internet and off the rosters.

i asked a guy in my department "do you know where so and so is", "nah man* (turns out he did).

i then asked this dudes best friend, "i wonder what happened to ***, he just vaporized off the planet, where is he, wonder what that dudes doing, he's a fricken legend, hahaha he trained me in this."

i asked these questions to these two a few times over 3 months, and from the first guy i always got "i don't know man", from the dudes best friend, i got death stares and silence.

i even jokingly made fun of some clumsy mistakes he made to his best friend.

turns out he died.

i fucked up so bad, and kept mentioning the death of this girls best friend to her constantly for months and she must've thought i knew, but i didn't.

i feel terrible and don't know how to apologise to her.

TIFU by asking a girl where her best friend was.
