John has a house. Whichever window he looks out of, he is facing south. He has windows on more than one side of his house. How is this possible?

At the North Pole, every direction faces south. If you're at the North Pole and look out any window, you're necessarily looking south. This unique geographic property explains how someone can face south from multiple windows. The South Pole would mean facing north from all windows, and the equator doesn't have this property.
