Extend the Story - Add a Room

Ah, no matter the times, her wedding is still maybe the biggest day in any girl's life. You rise early, to get your hair done for the final time, recheck your nails, confer with your younger sister about what is to be done.
You are Penelope Jenna Penderghast, elder daughter of the Penderghast family, shipping moguls of the East Coast, and today is your day.
You can't resist a whirl around your bedroom with your Vera Wang wedding gown held up to your slim, graceful torso; soon you will be sewn into it.
Everything, everything comes true today, everything you ever dreamed. Your mother could not be more exuberant, your father more proud, all your friends are in turns gushing like fountains or steaming with envy.
Plus you have a secret only your best friend knows.
Most of all, one fact is integral to the ceremony, its revealing to change everything.

You're really planning to run off before the wedding
