My family also hates the fact that I've started saying some things differently after watching some Australian YouTubers for a while.
For example, pronouncing "H" differently. Not quite sure how to explain it but there's a difference.
A few things America does differently that's just confusing;
I keep getting "fries" and "chips" messed up, thanks America for being so different from the rest of the world lol
Football and soccer. Why are they switched in America? Just why? FOOTBALL. FOOT. BALL. You use your feet to maneuver the ball, it's football, WHY DO WE CALL IT SOCCER OMG-
Biscuits are biscuits, quit calling everything "cookies" what the heck America?
There is also a mildly infuriating translation error in an anime I'm watching where they can't decide if it's tea or coffee. ... How does this even happen?
