Canadian Politics Today

I've been working my way through the complete works of Frank King's Gasoline Alley comic strip, which takes place in real time. It follows Skeezix from when he was a baby in 1922 and watches him grow. The strip is still published today, so he's in his nineties now (only the third artist since the beginning though, I think). Anyway, I'm up to 1937, and the most notable old-timey way of talking I found is saying you should do something when you think you shouldn't. Like "I should care what you think!" or "I should worry!"
I think that way of talking was still around when I was a kid, but it's pretty much gone now.

But yeah, 100% easy.
