I know nothing about rugby. In 13 years of living in South Africa I’ve attended only one live rugby match. But I know a lot about sports and I know a lot about people. And I know that Saturday’s Rugby World Cup final between South Africa and New Zealand was something I’ve never seen before: An entire nation of 62 million people coming together – forgetting their gaping divides, forgetting their country’s problems and all the world’s problems – experiencing unadulterated joy while watching a sports team that belongs to all of them.
