Shirts and jeans litter the asphalt, the empty fabric limbs askew as if they're attempting to escape. Blood smears Sarah's lips as she struggles against the chest of a dirty looking man with a beard. Terror. Terror is the only word my mind can seize on and it forgets what it means. I forget how to think - to move.

I was crying for the little girl I had been, who had withstood terrifying nightmares of death and blood and war and maiming. And when I had tried to share those horrors, the shock on my friends' faces had told me I was not normal, and I should keep my dreams to myself.

You could say that they were sweet, or you could say that they were something out of a horror movie.

Something as superfluous as "play" is also an essential feature of our consciousness. If you ask children why they like to play, they will say, "Because it's fun." But that invites the next question: What is fun? Actually, when children play, they are often trying to reenact complex human interactions in simplified form. Human society is extremely sophisticated, much too involved for the developing brains of young children, so children run simplified simulations of adult society, playing games such as doctor, cops and robber, and school. Each game is a model that allows children to experiment with a small segment of adult behavior and then run simulations into the future. (Similarly, when adults engage in play, such as a game of poker, the brain constantly creates a model of what cards the various players possess, and then projects that model into the future, using previous data about people's personality, ability to bluff, etc. The key to games like chess, cards, and gambling is the ability to simulate the future. Animals, which live largely in the present, are not as good at games as humans are, especially if they involve planning. Infant mammals do engage in a form of play, but this is more for exercise, testing one another, practicing future battles, and establishing the coming social pecking order rather than simulating the future.)

No child should ever be too sad to play.
