@roger,
It's the arrogance though, you defined your colloquialism as 'normal,' as Miss Toad is defining everything from an American point of view.
Whenever I give advice on English I don't use terms like normal, I say how it's spoken over here.
The language is English, it originated over here by my ancestors, and it's our language that was spread around the globe.
The majority of Americans are descended from people who had English as a second language which probably explains why you can't pronounce English place names correctly.
