From north to south
We first considered the words in the post below to be some kind of inspirational saying. At that point, we thought, “ah, ok, it’s just a little joke, like ‘two wrongs don’t make a right; three lefts do.'”
As it happens, it’s not one of those. We wouldn’t have thought to consider the truth stated in the post above, but it is now something we will never be able to forget. It also goes the opposite way, isn’t that right? You can travel west indefinitely and never begin to travel east, yet if you travel south enough, you will eventually start to travel north.
