The way that works, you start walking to school at 7ish, from a point on the sphere (visualize it at that "7am" point on a circle), going uphill. As you learn all day, the earth is rotating, and by the time you get out, the point has rotated to about 3pm. So now to get back home, you have to go uphill again.
I'm glad to be at your assistance.
