For some reason I can tell between accents really easily. Even the subtle differences. I don't know why, I just can.
I love the fact that different countries have different phrases and words for things. For example, one of my teachers at my high school is Canadian. She calls her grandparents mamma and pappa Stamp (that's her surname). You would never (well hardly ever) get a british person calling their granparents mamma and pappa _______.
Also, I think the candian's habit of putting the 'eh' on the end of a sentence every now and then, is quite cool. It's so pointless and random
