You see, I don't like Americanisation. Hearing Brits refer to the bonnet as a hood or seeing color instead of colour on hair products does wind me up. I'm torn because I know that language naturally evolves and English wasn't always spelt the way we spell now so there's nothing abnormal about our language evolving to use American words and spellings but I can't help but be that little bit irritated when I see it. Hearing the pronunciation of English swear words or place names butchered by an American accent also gets me - of course I understand it's not actually bad or personal and all that sensible stuff. It's just another thing that I pretend to not be bothered by!
You find it in a lot of authority figures. So many with authority can't stand to be questioned on anything, not least the thing they're supposed to have authority over. Teachers with education, police with the law, parents with parenting! They almost take it like it's a personal insult to be corrected or challenged.
