I'm from NC. My mom is from IL. Neither one of us can pronounce the word "horror." She pronounces it precisely like "whore" and I can't get over it. I, myself, dislike "harrr" movies.
Added bonus: I am a grown-ass adult and the only way I don't stumble introducing myself is if I do it like everyone else did growing up: by pronouncing the L in my name like a Y. I cannot pronounce my own fucking name and it's not even a disability. Usually, I just hope no one notices.
One of the more entertaining parts of learning another language is the extra attention to sound has made me super aware, more and more, of what speaking quirks I still have that weren't smoothed out by the midwestern influence which is considered to be the "general" American accent.
The lingering Chicago dictates random K's must immediately be followed by a Y (Shikyaaga!), but the southern part of me demands that any L at the end of a word is a W now and we're dropping consonants like we drop relatives when they come out as humanitarian. I'm horrified, I feel so bad for any foreigner who has to talk to me.
