Input: Text: tifu guys. my friend, lets call him "carl" has a surprise party tomorrow night, and im excited for attending. that was up to 30 minutes ago...

my friends and i, including carl have a massive facebook chat about random shit. there is a separate chat for organising the party. 

we found out that carls mum invited both his ex and current girlfriends to his party. we laughed, oh how we laughed. so, i told the massive chat, most whom are attending the party about his mum inviting her to his 18th.

i used the windows 8 facebook app. that only lists the people in the chat who are online. so, feeling that there was no danger (i thought there were only 4 people in the chat to begin with) in telling eveyone

i forgot carl was in that chat.

literal spam. all of it came over me as insults and threats of physical violence came from my friends, as i didnt realise until about 30 seconds later what i had done.

so, about 5 mins after, i open the planning chat and write a paragraph explaining my actions and declaring that i wont be attending. after that, people started getting edgey about what i coul do to ruin more shit

i did.

my friend, lets call him "john" told me not to bring carl into the planning chat as a joke. i said the following:

im autistic, but im not that autistic

at this point, i didnt realise that carls mum, the host of the party,   has 2 autistic children.

did i mention she also thinks im a drug dealer?

tomorrow is the big day. im expecting pure hatred and suffering from my peers, and if i even go, carls mum will surely kick me out. 

tifu reddit, tifu.

TIFU by ruining a surprise party and insulting the hosts autistic kids.
