I go for the spelling and pronunciation. It makes me feel far more normal when they look at me funny after I say something like "Ima gawn mosey awn up'uh pike a piece f'm'vittles." They talk funny, too. English is a funny language. I sat next to an Egyptian on an airplane and had a long discussion about how amusing accents were in Arabic and how amusing they were in English. She described the regional dialects in the Middle East and how Egyptians couldn't make head or tail of some of the other regional dialects. Those dialects may as well be different languages, not Arabic. She said she had a good time traveling around the US with her American husband, listening to all the dialects. She thought New Yorkers were pretty tough, so I gave her a concentrated dose of pure Carolina hill twang. The look on her face was priceless.
Point being that between the US and Canada, we have it pretty good. We speak the same language and can even understand each other most of the time. Even if Canadian bacon is what the English call bacon and what we eat is what the English call streaky bacon. I have that from a reliable source.
