Why Children Cry

Just as dogs, possessing certain heightened sensitivities as compensation for their lack of other senses, can detect when someone is at the door, and, consequently, often bark out in recognition, if not in alarm, do children cry. For dogs, on the one hand, man is at the door. For children, on the other, the messiah.

The dog either drools with excitement or pisses himself with terror, depending on whether he expects the man entering his house to be a friend or an enemy of his master, while the child similarly cries out in exclamation or for help, depending on whether it believes the messiah at the door to be a restorer or a destroyer of worlds.
