Yesterday was the 11th anniversary of 9/11. I heard Rudy Giuliani last night on CNN’ s Anderson Cooper’s 360 show. Giuliani, who was mayor of New York City that day, called it the “worst day and the best day.” The worst is obvious. But the best part—if we can permit ourselves to look for any silver lining at all—is all the stories of people living up to their Better Angels, in New York and elsewhere. One such story was what happened on 9/11/2001 in Gander, Newfoundland, Canada.
