Tonight at dinner Timmy said, "Everything looks crooked."
I asked him to explain what he meant by crooked, and he held his hand out horizontally to show me. "Instead of being like this," he said, his hand level in midair, "they're like this." He tilted his hand at an angle. He looked around the room at all the horizontal lines: table edges, picture frames, windowsills.
I wonder if he can see a straight line. I can't see a line and tell if it's straight, so I have no way of knowing what he's seeing.
