Imagine two countries that are neighbours as well as intense rivals.

At a border crossing, the armed forces of both the countries engage in a ceremonial parade, trying to outdo each other while being cheered and egged on by people watching on either side of the fence.

In between all the aggressive posturing, there comes a very human moment in which the main guard realises that his shoe is torn. But before anybody else can realise this, his rival counterpart helps him with such speed that everyone's pride remains intact.
