But by itself it is not an interpretation of anything. It is only a damn good interpretation to you and I because we already understand continuity. To a student that is just starting the journey, it is nothing but an example of what we are about to delve into.

To put a point on all of this. Our common sense interpretation of common sense is wrong, as is often the case with common sense.
