If they are like most young women these days, they won't marry and have kids for years, yet.
You're probably right. If people are serious about marrying for life, it's probably a good idea for a gal to spend about a decade enjoying her own company and deciding who she is and what she wants. Given that people spend 50-60 years of their lives as adults, that really isn't as much as it sounds like. But when the time does come, I'm sure Dubya's lap will be constantly occupied. You'll need the jaws of life to pry those kids away!
