A Joke Was Played on You

How far apart can a pair of happy enemies be? I am afraid that even if one is in the Antarctic and the other is in the North Pole, they will be pulled by some mysterious force and eventually meet, let alone "neighbors" who have been for many years. As the ancients said: "If you don't fight, you won't get to know each other." So we don't know each other if we don't "fight".
