An Alfred or a Jack?

I've been holed up in the ice reading Ken Follett's The Pillars of the Earth, figuring out my beliefs on nature vs. nurture. Will my children grow up to be Alfreds or Jacks, and can I do anything about it? For now, Annie is trying to type at the same time I am, so we can table this discussion for later today or tonight.

Here though, is a photo taken by my wife, that I love.
