Input: Text: (didn't happen today but i still fucked up) so a while ago i was over at my friends house (we'll call him john) for a little get together. john has a younger brother who has autism and spends the day in a room randomly clicking any video in the suggestions on youtube. he also makes loud noises and screams very often. we've been over at johns house lots of times before so we all know about his brothers autism and knew to be sensitive about it because the family have a tough time taking care of him. so we were all in the front room playing playstation and a few of the lads were on omegle. they eventually found a really good looking girl our age who was from spain but had really good english. they had a very civilised chat about the differences between life here and there was a bit of pathetic flirting and i was across the room playing the playstation. everything went quiet for a second and i heard a noise that didn't even seem human. i thought it was the spanish girl on omegle and i laughed and said "what the actual fuck was that". all of my friends looked at mr with blank expressions except for john who just sort of looked into his lap. i didn't realise that it was his autistic brother who had just been quiet for a while until the next day when my friends told me that john was pretty upset about it. i still feel really shitty about it.

TIFU by being an insensitive asshole
