Red's world, you see, is a closed circle. Not that it matters. I know that I'm a closed circle, too, and it's all I can do to find some starting point from myself, while at the same time trying to find my own terminus. There's no way I'm ever going to find my beginning or end in somebody else's circle. Two people together never add up to anything more than one person added to another. That we continue to add ourselves up in this way is the reason human beings will always be lonely.
