The conversation had become free-flowing and I raised my hand. Why, I asked from my lonely perch in the middle aisle, were all the whites sitting on one side of the room and blacks on the other? “It’s just always been that way,” one of the whites said. A black student nodded. “When we were younger we were all friends,” she said. “You didn’t think about black and white. But you get older, you hear things on the news. You look around. You hear the little things people say. Things change. We’re still friends but it’s different.”
