I spent about three years in Toronto for university, during which time I picked up the infamous Canadian "eh." I tend to forget how recognizable that habit is when I'm in Europe---most people think I'm just American because of my generic (well, whatever generic is) North American accent. But it was a dead give-away to the American girl that I was talking to the other day that I'd spent at least some time in Canada. It's really hard to hide it when you use "eh" like, 15 times in a matter of 3 minutes, eh.
The funny thing is, because I use "eh" so much, it's rubbed off on G as well. And G's British-pan-European English combined with the Canadian-eh-rubbed-off-from-Japanese-girlfriend makes for a pretty exotic combo.
Anyway, G and I are planning a trip to Toronto and NY in the summer, and I can't wait to go back to the land of Eh.
