Input: Text: this happened quite some time ago. i was in grade 3 and i was pretty innocent back then. you know, would not dare to swear. before i say anything, in my class was a autistic girl. she had assistant teachers constantly keeping an eye on her. it was lunch and i was sitting with some friends and she was at another table not to far away and she just kept on talking, which wasn't that common. recently before i heard my parents use the word "bitch" for some reason i thought it was not a swear word and it just meant someone who talked alot. so i called her a bitch. the assistant teacher watching her looked at me in shocked while i have this huge grin on my face not knowing what was wrong. see, nobody told me i did anything wrong. it was only a while afterwords when i reflected on what the hell i did.

TIFU by using a new word.
