During the few months Troy had been back home, he’d told his friends about us, and so we quickly eased into the conversation as though we’d all known each other for many years. They embarrassed us with great thanks for having served overseas. They recounted combat events Troy had told them, and we realized by the context of their stories that Troy had made us heroes for his friends because we’d been heroes to him. At this point I was the saddest I’d yet been over Troy’s passing, because the true friend from war is the friend who obliterates his own story by telling the stories of others.
