But we have the same bathroom floor—these white hexagonal tiles. If I look at them long enough, I can see all kinds of patterns in those hexagons: lines, arrows, even flowers. They kind of shift into these different pictures. It’s the sort of thing a person would never try to explain to anyone else, but once, when we were little, I told Sal about it, and then we went into his bathroom to stare at the floor together.
