Lol, I always tell foreigners we don't speak English, we speak American. It's origin is English, but we've added our own twist to everything, like dropping the u from colour. Happens everywhere really. May even be many differences in dialect in different areas of your country also. I haven't been there, but I saw a British guy once on a t.v. show and I swear it was everything I could do to understand what the guy was saying. Generally I do well understanding people who speak English as a second language without the subtitles the t.v. provides, but it was even hard reading those he was speaking so fast! Lol! Ah, the differences in us all that make everyday life all the more interesting!
