Let it never be said that the British don't have wry sense of humor.
My wager would be a daughter who'll be as close to her Uncle Harry and Aunt Pippa as she is to her parents; who will charm her way into the hearts of the entire United Kingdom because of she can balance being a noblewoman and a commoner; who will enjoy tramping about in the mud as much as she enjoys attending galas; who will attempt to join the combat arms branch of the British military (but might not succeed due to current policy rather than lack of trying); and who will be the royal scion to truly lead the British nobility into a new era.
