Imagine you live in a country where you could live your whole life never meeting a caucasian person in the flesh. Or even just somewhere that you'll not usually see one. Sure, they're on TV, but that's full of stuff that's different and far away.
Wouldn't it be nice to have expressions that you'll send to your friends and family look just a little bit less like that far-removed media and a bit more like you?
I couldn't agree more.
