There are 4 cardinal directions. East, West, North, and South. However, if you think about it, there is really only 2 true directions. Here is my reasoning.
If you go as far north as you can, then you will eventually hit the North Pole. You can't go any further north than the North pole, because any way you go from there is South. Same with going to the South pole.
However, it is not the same for East and West. You can go as far East as you want. There is no East Pole or something like that. Also the same for West. no matter how far East you go, you will nevr suddenly find yourself going West. So we come to this dillemma: there must be at least 2 subdivisions of directions. So..... which pair is the "true" piar of directions? Please tell me if my reasoning is flawed.
