Input: Text: so my company uses an internal chat messenger program. i saw my coworker's status was online so i just assumed he was in his office and i could talk to him anytime. later in the day my manager asked me for a status update, and i told him i was working with my coworker to get it done. well i actually hadn't even started on it and went to my coworker's office to start talking about it. i looked inside... and he wasn't there! even though his chat status was online, he was actually working from home. just as i was about to leave, my boss was walking down the hallway and saw me in front of my coworker's office looking like an idiot. so now my boss realizes i was lying to him when i said i was talking with my coworker... because if i was actually talking to him, how the fuck did i not realize he was working from home? i am so fucked.

TIFU by not realizing my coworker was working from home
