"Once upon a time there were two countries, at war with each other. In order to make peace after many years of conflict, they decided to build a bridge across the ocean. But because they never learned each other’s language properly, they could never agree on the details, so the two halves of the bridge they started to build never met. To this day the bridge extends far into the ocean from both sides, and simply ends half way, miles in the wrong direction from the meeting point. And the two countries are still at war."
