Did You Know?
If you keep going North, you will eventually go South but, if you keep going East, you will never go West.
North and South are different from East and West in that North and South are absolutes — you can go north only until you hit the North Pole. Once you are at the North Pole, any direction you go is South, and the same thing at the South Pole — there, any direction is North.
East and West, though, are relative. There is no “East Pole” or “West Pole”. Any point on Earth is east of somewhere and west of somewhere else. You can keep going East or West forever, and just wrap around the Earth again and again.
