People often remark that Canadians are very polite. I think I would have to agree. For the most part we use the magic words – please and thank you – and of course we have been known to apologize from time to time. Yesterday I noticed a new aspect of our politeness when I passed a parked police car downtown and spotted a friendly warning on the rear window.
The window is equipped with bars on the inside to make sure no one kicks out the glass, and there is a partition between front and back seat. But what struck me was that printed on the window was a warning: attention à votre tête or watch your head when getting in.
Such a nice touch!

Nice touch, indeed! 🙂 (And I’m glad I never noticed that before! 😉 )
I have seen signs around here on steps: “WARNING! STEP UP!!”
