Input: Text: a bit of background, but i immigrated to america early in my life. so when i started grade school, i knew nearly nothing about american culture or the english language. 

sometime in 2nd grade, my class was having some sort of discussion about stereotypes and my teacher was trying to get us to talk about irish stereotypes, since she was irish. kids were mentioning things like leprechauns, shamrocks, etc. then one kid mentioned having red hair, which gave me the idea to raise my hand and say that they also had red necks.

needless to say, i didn't realize the depth of my words and was forced to sit outside for awhile. for the rest of that day, my teacher and other kids were sending me dirty glares and she unwilling to pick my hand for months.

TIFU by accidentally calling my Irish teacher a redneck.
