In the dark, fluid warmth of a mother's womb, two babies float side by side. The first baby turns to the second, voice barely audible above the steady rhythm of their mother's heartbeat.

"Do you believe in life after delivery?" the first baby asks.

The second baby responds without hesitation. "Why, of course. There has to be something after delivery. Maybe we're here to prepare ourselves for what will be later."

The first baby scoffs. "Nonsense. There's no life after delivery. What kind of life would that be?"
