London stayed functional during the Blitz, months and months of nightly bombing and not knowing if the next one would be poison gas, or the prelude to a German invasion. People slept in shelters all night, went home to change clothes and check if their houses were still there, and then went to work. When I'm scared, which takes something pretty big, I think of that bravery and decency, and I make it through. I'm thinking of London today - and Madrid - and I feel sadness and anger. But most of all, I am filled with admiration for Londoners' understated and unbreakable valor, even in times darker than these.
