by : $327$

 * Two Paradoxes

Solution

 * $(1): \quad$ As you go over the pole, and are facing South, so also are West and East changed over.
 * So, without turning round to face North, West is already on your right and East on your left.
 * So when you turn round to face North, West is on your left and East on your right, and all is well with the world.


 * $(2): \quad$ When you look in a mirror, it is not left and right which are exchanged, but front and back.
