Your first brush with reality will be the realization that everyone has neglected to tell the baby when he or she is due. Sure, you've known for months. The doctor whipped out one of those nifty circular slide rules and gave you the precise date and time and astrological sign. You've notified your employer of which days you'll be out of work, and you've arranged for your in-laws to help out. Your bags are packed and lined up in the hallway.
Days go by.
You start to remember everything you've heard about children not wanting to leave the nest, and you realize this kid's never coming out. You ask the doctor about inducing, and are told to be patient. Meanwhile, your wife's abdomen has made the short list of sites for the next Olympic opening ceremonies. Or, there's the alternative scenario. You're weeks away from the blessed date.
