"Were you named because of that weird, dead king?" America asked thoughtlessly one day. "You know, King Arthur, the whole Camelot thing. Sounds like the place where all your imaginary friends live."
"America, I don't want to deal with this today," England told him calmly. It was hard for him not to snap at the other about what he'd said.
"C'mon, England," America whined. "Do you really believe that stuff?"
England stood up, facing America across the table. "Of course I do! It really doesn't matter if I do or not! There are lots of people who don't really believe he existed but they still live for him. The very idea of King Arthur strikes up passion in people. His words give people hope. He teaches people to be valiant and to follow their hearts. What's so wrong with that, America? Why criticize a dream?"
"I'm not criticizing you," America said with gentle words. He was smiling tenderly, his cerulean eyes were soft. "Or mocking you and King Arthur."
"Then why the skepticism?" England demanded. "You're always like this. Why must you be so hard to understand?"
"I just love seeing you so passionate."
