Everyday English Example
Here's a personal story. The first time I heard "through the roof," I was in elementary school. I was what people might call a child prodigy, always getting top grades. My teacher told my immigrant parents that my grades were "through the roof."
At the time, I had no idea what that meant. I was completely clueless. I actually thought I was in trouble and braced myself for punishment. Contrarily, I later learned that it meant my grades were excellent, at an extremely high level. That one phrase taught me an important English lesson I never forgot.
