Just a heads up

Whenever my students chose British articles or texts for class discussion, I have to do a lot of googeling to figure out what the heck is going on.
And then I tell my class; you know, you can say it like that...and it's not wrong. But if you're in Idaho, nobody else is going to be saying it like that. 
Side note: last week in class one my students made a joke. In English. I was so proud.
