where i'm from we apparently pronounce tour differently i've been told (we say like tore), and someone pointed it out to me and i was like whatttt the heck.
I pronouced dachshund as "dash-hound" nearly my entire life, but then I learnt a few months ago that it's pronounced "dox-hund". I was pretty embarrassed.
ahhhh-- my boyfie pronounced spearmint wrong until 2 years ago (hes 26 now)
he use to say spare-mint, the first time I heard him say it I was so confused hehe ; v;
