Actor Matt Damon has explained how he hopes to teach his children how to make a difference in the world. "The way you have to parent them is to show them the world," Damon revealed at the OneXOne children's charity event in San Francisco. "Explaining the world can only go so far. You can read about devastation every morning – it's on the front page of the newspaper – but when you actually go there and see it, you realise this isn't something you can turn the page on."
