one evening, after a long day, I showed up to dinner and saw a group brandishing the Confederate battle flag. I don’t know what got ahold of me. I don’t know why it was right then. But I understood that this was a matter not of public history but of deep belief. I quietly excused myself and went to my room. Even then I remember not wanting to make a scene or in any way disturb my hosts. But the next morning, they apologized profusely. They knew.
