The World Cup team from Japan made news the other day when it was revealed that they… wow, you should probably be sitting down for this… cleaned up and made their locker room look like no one had even been in there. Apparently, the Japanese fans have done the same and picked up trash around their seats after the matches.
I guess this is news, especially here in the U.S., where such behavior might be viewed, at a minimum, as strange and unnecessary. It’s really a principle similar to what we were taught in Boy Scouts—leave the campsite in better condition than you found it.
Clean up after yourselves.
But that reeks of a certain humility and consideration of others, which is somehow… un-American?
