Kate and Mary
Being from a point so much further in history than Mary, Kate could have confirmed her worry that her son likely ended up fighting in the second World War and told her how dramatically fighting two bloody conflicts back to back had changed the United Kingdom and Europe. Even the United States had seen significant changes and, aside from Pearl Harbor, none of the fighting had happened in the country.
"I can't imagine," she told Mary with a slight frown. The closest thing Kate could come up with were the terrorist attacks in 2001 and how helpless and terrifying it had been in New York City in the aftermath. She had been in college when it happened, studying criminology at NYU, far enough away to miss the worst of the horror but close enough to feel the hysteria that had gripped the city. But that had been a few months, not years of her life. "It's a terrible thing to have to live through."
