> Like when I told her that my parents' hydro had been out all day.

When I immigrated to Canada (Ontario) a decade ago, the term hydro was the most confusing to me. I assumed it meant water supply or plumbing, but it was always in the wrong context. I imagined the disaster of hooking up the plumbing to the electrical service! Now it’s completely natural to call it “hydro” but confusing at first.
