Input: Text: this happened in high school, about 5 years ago now. 

quick bit of background. part of a geography field trip was for us to go to a city with a large ethnic population. being britsh, that ethnic group tends to be asian; pakistanians, indians etc. while i'm there, i'm in a part of this city with my small group, a fair few feet from everyone else. i'm approached by this asian guy who asks me what i'm doing here (he seemed quite defensive rather than intrigued) so i tell him i'm on a school trip and ask him what ethnicity he was.  he responds with "oh right. i'm pakistani. just don't see many white people around here" and walks off. no white people in england? i was a little bewildered. 

on to the fuck up. i'm in my english class and my teacher is asking us about how the trip went. so i start to tell her the story, saying something weird happened to me. she asks what that was and what follows is close to what was said. 

me: "so i was doin my work and this paki fella came over and-"

teacher: "/u/razoman you cannot say that! that's terrible!"

me: "what, why is it?"

teacher: "it's racist!"

right now i'm bricking it; i'm dead against racism so i try play it off with a joke. 

me: "no it's not, it's just short for pakistani. the same way an irishman is irish, a british person is a brit and a frenchman a cunt!"

i got suspended for a week.

TIFU by explaining I wasn't being racist by trying to be funny
